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.
