It's not a theme, just some basic color palette with green for preprocessor, yellow for keywords, cyan for string and numbers and white for the rest. Dark gray for the comments.

Re: animations - yeah, they are all custom, but there's not really much to them. The hardest part was to do flickerless fade-ins and -outs, the code for that just ain't pretty. Window transformations are just DeferWindowPos with the right combination of flags and a bit of painting cooperation from custom controls. Still though... the amount of work required to get these animations working was ungodly compared to $('div').animate({ ... }); :)
