THiNK about |PROG|RAMMING

What was the last nontrivial program you wrote, and when was that? Feel free to substitute with your current project if the last one was embarrassing. (Me? Currently: a procedural network wiring system for something too boring to describe. Previously: a prototype version of that boring something, completed a few months ago.) Being intentionally vague so I don't come off as an attention whore.

And by the way, have you read your SICP today? I'm reading mine right now.

A multithreaded calculation system to extend realistic, virtually real time distortion and dissection to an active 3D polygonal scene that uses indexed point geometry.  I'm trying to do a "take that" against the PS3.

At the moment, I'm actually doing underbelly work involving file IO and optimizing the vertex (re)indexing algorithms.
