Believe it or not there was a demo on the original Apple Macintosh PowerPCs called Gerbils! On the CD for OS 7.5.x there was a demo to show off the new-and-improved performance. Each time the demo was run it would generate a random track resembling a rollercoaster. Except instead of a coaster on the tracks there were a number of gerbils. One of the views was from the point-of-view of the gerbil, along with above, in front, and so on. Also, just about any 3D QuickTime model could be imported instead of the gerbil, for your viewing pleasure.
