The special edition of Japanese Dreamcast/Playstation 2 game Rez included a device called the "Trance Vibrator", which plugged in as a controller and was meant to go under a couch pillow and vibrate from there, so someone playing Rez would feel like they were in a club. People soon found another more obvious use for it and eventually Rez became infamous as "that techno PS2 game with the sex toy."
Both the game and the TranceVibrator are long out of production but if you ever manage to get your hands on the latter, you'll be happy to know that not only are there now Linux and OS/X drivers for it (built off of the previously-available FreeBSD drivers), but also a replacement for the Unix finger command which—oh hell, we'll just let you read from the program instructions:
This program is a rudimentary teledildonics application built around the finger daemon - hence bringing generations of CS undergrad innuendo full circle.
It has two modes in addition to what you're seeing now - if you finger [any string]@[this host], a series of random pulses will be generated, proportional to the length of the string.
Alternatively, fingering 0x[hex digits]@[this host] will instead send a direct stream of motor speeds to the vibrator, one per second.
If anyone reading this actually has this set up, send us an email and let us know!
