The acronym stands for "Virtual Light Machine", a name I coined a couple of years before William Gibson published a novel called "Virtual Light" :-). The VLM sequence is my most recent work in the field of lightsynths. VLM v0 was a non-commercial setup which ran on a custom Transputer system lashed up in my old 286 PC. VLM v1 was built into the CD-Rom addon for the Atari Jaguar videogame system. VLM v2 is currently available on the Nuon DVD platform, and is built into Nuon DVD players built by Samsung and Toshiba.
