Acid was one of the first computer art groups to enter the scene. They make Ansi Pics (For those that remember the BBSing days...), and well as RIP (was supposed to be the new big thing a few years ago but died off pretty fast), VGA , jpegs, and gifs... They also make some techno music and other misc stuff...

Here's a couple pages with some of their pic's... (recommend a decent speed connection...)
