The Null Device
There is apparently an entire subculture in the US of people who build sex machines. So much so that the Museum of Sex in New York is having an exhibition on the subject, and for those not in New York, there is a book.
These are tinkerers, people who like to mess with all things mechanical. And they have a sense of creative invention — they are proud of these things when they create them. But also they think about sex a lot and this is what resulted from that combination. It's not just a sculptural thing. They are making it for a purpose. A number of them are married, they are making it to try and introduce something to their wives. Some may be using it to attract women — or they think it might attract women. And for some of them it's a business. But they are not part of a scene, like a sexual scene. It's more that they got the idea independently that this is something they wanted to make, they wanted to have.The machines look like anything from dentists' chairs to Luxo lamps, with conspicuous plastic appendages attached. One appears to be a modified sledgehammer, and looks frightening. There is even a coffin-shaped one built by a couple of goth kids (aww, isn't that cute!).
A hardware hacker with a very steady hand builds a head-up computer display into a pair of slim-line sunglasses. His ultimate goal is to fit sunglasses, a video camera and a microphone, covertly, into what looks like an ordinary pair of sunglasses, effectively making a Snow Crash-style gargoyle rig (just add a wearable computer).
