Okay, I know screensavers are bullshit nowadays, but I really like some of the ones I can find. I've recently been entranced by Nvidia's Geoforms, but that tends to crash my system from time to time. I was wondering if anyone knew of any really nice, professional screensavers out there, preferably free. No 3d aquarium bullshit, but something that really pushes the envelope. Geoforms for example is heavy on the graphics but very freeform and flowing. Anything that really makes the GPU / CPU work is something to ponder. Maybe even something comparable to SETI.
