The blurb below is from the 21 Jan 2002 issue of The Harrow Technology Report:
Fifteen years ago, when Pixar introduced its then-amazing computer-generated video titled "Luxo Jr.", it required 75 hours of Cray supercomputer time to render each second of photo realistic animated video. Today's GeForce 3 chip in many PCs can now render similar video in real time!
With computer performance increasing exponentially, it's easy to lose track of how far we've come. I remember being blown away by Luxo Jr. when it was first released, but now it's no big deal.
