Actually, it's 100 frames and three hours. The first image was taken at about frame 10, the second at frame 20, the third at 77, and the last image at frame 91. The animation runs from frame 0 to 100. I was playing it at 30 frames per second, so it took about an hour for each second of animation. I had raytracing and refractions turned on, production quality at highest res, and a 640x480 screen. (not sure if I needed refractions turned on, though. don't even know what it does!)
