The game takes place in a virtual world inside a computer. You play a hacker of sorts, flying through six levels of cyberspace in search of the artificial intelligence at the heart of this world.
Every time you destroy one of the insect-like enemies, a sound is generated. This sound becomes a form in the scrolling, flashing 3D computer world rushing past. Destroying enemies in patterns results in more elaborate sounds and effects, literally creating the music and the graphics on the fly.
"We worked closely with the artists within the game, breaking down the tracks to the most basic of notes then putting them all back together to fit in with the game structure," Mr Mizuguchi told BBC News Online. [...]
"We have a vision that people will be chilling out with friends," said Mr Mizuguchi. "While one person is playing Rez, the others can watch the visuals and listen to the music."
That's why I was so excited by Rez's trance vibrator, since it seems to have no other purpose than to act as a masturbatory aid. Its shape is pretty nice, it can slip easily under your skirt or in your panties, it comes with a protective "glove" which you can wash, and it emits a regular pulsating rhythm that gets ever more intense and thrilling the deeper you go into the game. Damn, by the end I was writhing on the floor! Synesthesia indeed.
