I hope this is the right place to ask this question. I've been trying to remember the name of a program I used to play around with on my Mom's Mac years ago. I think she had a PowerMac 7100, 7200 or 7500. I remember the 7 part I think the program was a screensaver. It would let you select some varibles like size, planet, etc. and then create a fly-over of a random planet's surface made of little polygons. I wish I could give a better description but its just on the tip of my brain.
