My source is from the current issue of "World UNIX & C",
Vol. 5, No. 4, published by Springer-Verlag.

The article, "Computerizing the Movies at Lucasfilm: A Little UNIX,
a Lot of Brute Force", by Michael Hawley, cites the following in
describing the film "Andre & Wally B.":

	Duration: 1.4 minutes
	Resolution: 512 x 488 pixels
	Animation controls: 809
	Polygons/frame (average): 2.9 million		(I got this wrong)
	Time to render a frame on a DEC VAX 11/780:
		1-2 hours and 6-8 Mbytes
