Show me a working program you built in Lisp.

I see a lot of ``faggots'' here claiming to have achieved Satori and becoming [b][i][o][u]EXPERT PROGRAMMER[\u][\o][\i][\b]s after reading SICP, but I have yet to single /prog/rider demonstrate a working program they've built. Show us what you and Lisp can do. I'm legitimately curious.
