San Francisco has a store that bills itself as the largest independent pirate supply store in the city.

I don’t know if it is in fact the largest pirate supply store in San Francisco or not, but it is indeed a large pirate supply store. lapis_lazuli and her partner brought us there in part because I needed some pirate supplies, and in part because it’s a cool place to visit.

The store sells really cool hand-made cast-iron padlocks. My sweetie zaiah has a large cage which will be part of the dungeon furniture once the dungeon is finished, and every cage needs a hand-made cast-iron padlock, so the pirate supply store turned out to be just the right place to visit.

The very cute young cashier who sold me the padlock asked me if I already had a use in mind for it. I told her that I did, and that would have been the end of it, except that she kept on pressing. “What do you plan to use it for?” she asked.

“A cage.”

“Like a cage for a dog?”

“Not exactly, no.”

“What kind of cage?”

“A big cage.”

“What’s it for?”

“It’s part of the dungeon.”

“You have a dungeon?”

“We’re building one, yes.”

“What kind of a dungeon? Like for–”

At that point she turned a brilliant shade of red from the tips of her ears down to her toes and started saying “Oh my God” a lot. She also started stuttering quite a bit and generally looking flustered. Finally, after a lot of “um”s and “err”s and a bit of hand-flapping, she said something about it taking all kinds of people and turned away.

That was the second most fun thing that happened in the pirate supply store, for some value of “fun” that means “I don’t believe in protecting people from the results of their own questions.” The first most fun thing was when lapis_lazuli took me by the hand, looked me straight in the eye, and said “kiss me.”

Which I did. And then did again. She’s rather a nice kisser.

Smart, confident, direct women are sexy. Ahem.


The Porn ‘n’ Cupcakes, the tour of the submarine, and smooching lapis_lazuli in a pirate supply store all aren’t directly related to finding myself in a seedy motel room in Seattle with a bullet hole in the window and a door that looked as if it had been kicked down repeatedly, watching a tattooed grad student in striped socks having a huge screaming orgasm, but they’re indirectly related in the sense that I can perhaps be forgiven for having sex a little bit more on the brain than I usually do during the drive back to Portland, and to the idea that would inevitably bring us to that motel room in Seattle, to which I am by degrees coming.

In fact, the trip to MacWorld led to two different instances of watching a pierced, tattooed woman having a screaming orgasm. This story has several branches, which I’ll get to later.

At this point, the genesis of that idea that brought me to Seattle was less than twenty-four hours and a quick side jaunt through Shasta Caverns away. That side jaunt deserves a bit of talking about of its own.


Shasta Caverns is a cave system near Shasta Mountain, which has an interesting history. It was, apparently, discovered in 1878 by a Native American fishery worker who’d been out hunting and followed an animal through a small hole into what he believed would be a tiny niche in the mountainside.

Scott and I stopped at Shasta Caverns on the way back to Portland partly because our original plan, to head back along the coast and take pictures, was thwarted by reports of rain.

The cave system at Shasta Caverns is accessible only from the top of a mountain across Lake Shasta from the road. Entrance to the cave system involves taking a WWII-era landing boat across the lake, then taking a bus up a very steep, narrow, winding trail that’s so curvy in some places that the bus actually overhangs the edge of the road when it’s turning. The buses themselves were carried across the lake by that very same boat;, which was barely big enough to accommodate them; the guide said the landing ramp can’t be raised while a bus is on the boat, meaning that a ripple any bigger than a matchstick will swamp the boat while it’s transporting them.

The mountain itself looks like this from the edge of the lake.

I still have yet to get used to how folks just leave scenic natural wonder lying around all over the place here in the Pacific northwest.

The cave itself is small but quite spectacular. Unfortunately, a guided tour is the only way to go through it; visitors aren’t allowed to wander about on their own, the way they can at Carlsbad. Which is a damn shame, because I’d love to return here one day with a model and do some nude photography in this place.

Scott and I lagged behind the group as much as our patient and remarkably tolerant guide would permit, shooting long-exposure images from a pair of tripods. The cave system is small but spectacular, and features every type of rock formation that can exist in a limestone cavern.

After we left the cave system, through an exit five hundred feet or so above the entrance, we were confronted with this view:

At the very peak of the caverns is the remnants of this rusted ladder, which for nearly a century was the only way in or out of the cave system. The hole in the ceiling is the original entrance through which the cave’s discoverer made his discovery.

Detour complete, we hopped back into Scott’s car and headed north. That’s when it happened.


Scott has a habit of listening to books on tape via his iPhone whenever he travels–a habit which, by the way, I endorse.

On the trip down, he had introduced me to Wooster & Jeeves, which is pretty funny stuff. On the way back, he opted for something a bit different: Mind Wide Open: Your Brain and the Neuroscience of Everyday Life by Steven Johnson.

I’m not quite sure what made him choose that particular book. Maybe it was simply the next one in the queue. Maybe he’d decided that entertainment a bit more meaty than turn-of-the-centry tales about an incompetent buffoon and his hyperconfident butler might be suitable. Perhaps it was entirely random, and the hand of fate reached out to touch him. In any event, the moment he pressed “play,” the dice were cast, and the Seattle motel room became inevitable.

The book, you see, talks about a company called Neurosky.

Neurosky makes a single-chip EEG device that’s designed to be embedded in small electronic toys and gadgets. Neurosky got into business making neurofeedback devices–gadgets intended to train a person to control her own mental state by analyzing her brainwaves and then providing some sort of reward for reaching the goal state.

Their earliest gizmos were video game controllers, which would read the player’s brainwaves and let her control some part of the video game accordingly. They made a race car game, for instance, in which the harder the player concentrates, the faster the car goes.

More recently, Neurosky has started making chips for other companies. One of their customers is Mattel, who makes a toy called the MindFlex, in which you move a ball around by concentrating on it. The game has a motor connected to the chip’s outputs, so that when you concentrate, a fan blows and levitates a ball in the air.

Pretty cool, I think, for the first five minutes, and then probably quite boring after that.

To me, though, in my already riled-up state (and to be fair, my baseline state is pretty riled up to begin with), the connection was obvious. Here is a brain-scanning device that could be used to activate a motor.. Think about that for a minute.

A brain-scanning device. That could activate a motor.

The idea hit like a lightning bolt. If a MindFlex could turn on a motor attached to a fan, surely it could turn on a motor attached to something else, too. Like, say, a vibrator.


It was Twitter that provided the last bit of the puzzle.

On the drive home, I tweeted, as I always do. “Is sexual arousal a discrete brain state?” I said. “Can you use neurofeedback to condition it?” All good questions, I thought. That’s the nice thing about neurofeedback; you can use it to train yourself to be able to go into a certain metal state, like meditation or concentration, at will.

So why not apply the same idea to sexual arousal? If an EEG could detect sexual arousal, ad run a vibrator whenever the wearer became aroused, could it become a neurofeedback training device to teach people to become aroused whenever they wanted? And more to the point, wouldn’t be fun?

There are a lot of folks who read my Twitter feed. One of those folks is partnered to a neurobiology grad student who was thinking along similar lines, although for entirely different reasons. Shortly thereafter, she got in touch with me.

Of course I’d like to collaborate on a project involving hooking people up to an EEG and getting them aroused to see what happens…I mean, really, does the question even need to be asked? It’s Science, right? Science is something I’m in favor of, after all.

So you see, the seedy motel room lurking in my future was all part of the great enterprise of Science, the noblest of all human endeavors.

Tandoori! For SCIENCE!

The time for mad science is upon us! After a couple of weeks of herding cats, it is time to take the first step toward my plans for world domination through brainwave-controlled sex.

Tomorrow, we head off to Seattle, where we will spend the day hooking folks up to an EEG machine, getting them sexually aroused, and seeing if it results in a measurable, quantifiable change in observable brainwave patterns.

If the answer is “yes,” the next step will be to see whether or not a Neurosky EEG chip can be programmed to spot that change; and if the answer to that question is “yes,” then the next step after that is to see if it’s possible to make a vibrator that can be controlled by thought.

Well, kind of. A vibrator that responds to arousal state, more precisely, but close enough.

And then, world domination!

Though not the kind Steve Jobs approves of. During the process of trying to work out transporting the EEG machine from the place where it’s stored to the place where the mad science will be occurring, my iPhone made some…interesting word substitutions.

Random psycholinguistics musings

A couple of days ago, while I was in the shower, I started thinking about an old experiment that one of my former professors had talked about in one of my linguistics classes way back in the dim days of my misspent youth.

If I recall correctly, the experiment, which was done in the 1940s or 1950s and for which I sadly don’t have a citation, was one of the endless series of attempts to ‘prove’ the superiority of whites that were so trendy back then. It involved taking random lists of numbers and asking folks of different races to memorize them.

The results seemed to fit with the racist orthodoxy of the time. Whites and Asians performed best, learning to memorize longer lists of numbers more successfully than, say, Africans.

But another researcher noticed something interesting: success at learning to memorize long lists of numbers varied not with the race of the person doing it so much as with the language of that person. In English, all of the numbers between one and ten are single syllables, except for “seven,” which has two. In Japanese (I’m told), all of the numbers between one and ten have one-syllable names. In some other languages, some of the numbers between one and ten have multiple syllables.

People’s performance on tests involving memorizing numbers varies not with the race of the person, but with the person’s native language, and more specifically with the number of syllables for the various digits in that language. whose native languages were English or Japanese outperformed people whose native language contained many terms for digits that were two or three syllables long, regardless of their race.

When we memorize a list of numbers, it seems, we’re not memorizing the shapes of the numbers or even a concept of what the numbers mean; we’re memorizing words. We rehearse the list of numbers as though we were hearing it or speaking it. (This definitely seems to be what I do; if I’m trying to remember “813-555-7123,” what I do is I say the numbers to myself: “eight one three five five five seven one two three.”)

So that got me to thinking about whether or not what psychologists and cognitive scientists call the “short-term buffer,” which is the place where we stick stuff we’re trying to remember right now, has a limited capacity in terms of syllables as well as in terms of chunks. (The notion that we easily remember lists of seven plus or minus two numbers depends on how we chunk them; I remember “1966,” the year I was born, as a single chunk, not as four digits.)

Anyway, while I was washing my hair, I started wondering if the same concept applies to things other than numbers, such as arbitrary lists of shapes. Imagine a list of shapes, laid out and named like so:

Some of these shapes have names that are one syllable long, some have two-syllable names, and some have three-syllable names. To front-load the experiment, the researcher could describe the shapes by name (to ensure that everyone was using the same names for the shapes), or could even give all the test subjects a copy of this chart.

Now, if there is a correlation between the number of elements that can be stored in short-term memory and recalled and the number of syllables that the words for those elements have, then I would expect that people would consistently do better when asked to memorize lists like dot-dot-square-grid-circle-dot-ellipse-square than lists like triangle-triangle-square-rhombus-hexagon-triangle-ellipse-square. Performance should vary not only with the length of the list but also with the number of syllables in the names of the shapes in the list.

So yeah, that’s the kind of thing that runs through my head in the morning. Anyone want to fund me?

Playing mad scientist

A couple weeks ago, a friend and I drove down to San Francisco for MacWorld.

That’s not actually what I’m going to talk about. We met some folks, toured a submarine, and explored a cave system, but that’s not what I’m going to talk about either.

Instead, what I’m going to talk about is sex. And brain research.

On the drive back, we were listening to a book on tape about neurology, which talked a bit about a company called Neurosky that was making brain research available to everyone. And it talked a good deal about neurofeedback, and learning to change one’s brain states at will by using neurofeedback devices.

Now, Neurosky makes a full-fledged EEG machine on a chip. It’s starting to show up in toys, like the Mattel Mind Flex, which teaches meditation by reading the user’s brainwaves and letting the user control the toy with her mind.

Which, as I’m sure you can anticipate, got me to thinking about sex.

So the thing I’ve started pondering is the notion of a gadget a bit like the Mind Flex, only that runs a vibrator or some other sex toy. Which got me to wondering if sexual arousal, like meditation or concentration, is associated with a characteristic set of brainwave patterns.

So I am talking to someone in Seattle with a similar interest, and she might be able to get me access to a brain lab and an EEG. The first step would be to find out if sexual arousal can indeed be identified by a specific pattern of brainwaves. The next step would be to see if the Neurosky chip can be hacked to detect that pattern, and to run a sex toy like a vibrator. The third step would be to see, if all this works, whether or not it’d be feasible to actually build a self-contained, brain-operated sex toy system.

So for the first part, I am looking for volunteers willing to go to Seattle, get wired up to an EEG, and sexually aroused while their brainwaves are recorded. There are a few folks who I’ve talked to who are interested; any more takers?

Link o’ the Day: HIV Visualization

From the Russian company called Visual Science comes this absolutely stunning 3D visualization of the human immunodeficiency virus:

From the article on the Web site:

HIV virion is a roughly spherical particle with a diameter between 100 and 180 nm. Virion is surrounded by cell-derived lipid membrane containing surface proteins. Some of these proteins are products of viral genome (surface glycoprotein gp120/gp41) and others are captured from the host cell during viral budding (e.g. ICAM-1, HLA-DR1, CD55 and some others). The gp120/gp41 glycoprotein interacts with receptors on cell surface promoting fusion of virus and cell membranes. Other surface proteins found in HIV perform supporting functions. […]

The HIV genome is approximately 10000 nucleotides long and contains 9 genes, which encode 15 different proteins. The most important viral genes (open reading frames) are Gag, Pol and Env. Gag encodes the p55 protein, which is subsequently cut into structural proteins: MA, CA, NC and p6. Pol reading frame encodes integrase, protease, and reverse transcriptase. Env encodes the two subunits of the surface glycoprotein complex. Other genes (Tat, Rev, Vif, Vpr, Vpu and Nef) produce accessory proteins, which modulate host cell metabolism and facilitate different stages of HIV life cycle.
