Currently it's a complete dog's breakfast of scripts and hacks. People seem to like it, so I might look to package it properly, unless someone else wants to do it.
I curl the tweet, look for references to other tweets, curl them, lather/rinse/repeat until there are no more. Then I build a dot file and call GraphViz on it.
Trivial stuff - people seem to like it, and I've found it very useful. I should learn how to use GitHub and throw it up on that.
