At SIGGRAPH 2004 and BrickFest 2004 DC Tim Courtney and Orion Pobursky showed a 2 minute POV-Ray animation created by Anton Raves and rendered by James Reynolds...

...at the University of Utah Student Computing Labs' Macintosh computers using the Xgrid software. The Xgrid software makes it extremely easy to create ad-hoc computer clusters. For this animation, about 130 computers were used, about 80 of the computers were 2.0 GHz dual processor 64 bit G5 PowerMacs. Some of the frames with the most bricks took as much as 8 hours to render. With over 3000 frames, there is no way one computer could ever render this.
