DaMavieMan, I'll second Monroeville and suggest the lightcycle sequence. He has plenty of good ideas about how to spice that up.

Monroville said:
Personally, I thought they were supposed to have GREY faces throughout the whole movie, not flesh-toned (being they are programs without blood and all).

On the surface, that stands to reason. But remember that the in-computer scenes were shot in black and white, with all of the color added later. So they had to take extra steps to add the color to the faces. The flesh tone they used is a very muted sepia tone.

See this shot for example:
