I see this kind of thing all the time. On my PC, the Faustus is gray. On my friends it is green. The problem is that something along the line is/was 16 bit, and is improperly converted to 8 or 32 bit, or vice versa. In 16 bit, green has an extra bit-per-pixel, and things are always screwed up, and grayshades have a green appearance to them. It usually is a video card rendering conflict, combined that you cannot have a shade of gray in 16 bit color. I think the green looks cool, but whatever. It's what you have to expect from the crap that 16 bit is. Oh yeah, the shinemaps certainly do emphasize the "problem".
