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.

I fucking knew I was going to need make this clarification: a ``working program [you've] build'' does not mean ``some completely useless 10-LOC function you lifted from a textbook''.

At least it wasn't lifted from the first chapter of SICP like I was expecting though.
