Pycraft has remained relatively obscure. It lets you write (very close to) Python code in the minecraft chat window to perform magic that's written in Python code on the backend. I thought maybe a few demos showing what you can do with the code might serve to interest a few others in playing with it. The code consists of a Java plugin that exposes much of the Bukkit API over a form of json-rpc and a Python client that talks to that API.
