Well, I started off in July wanting to do a rewrite of Bunny Slayer, but that didn't really get off the ground. Instead, I ended up working some libraries and did some general cleanup.

Blackthorn Starter Pack

One of my goals for a long time has been to make it as easy as possible to compile and run my game from source. As a step in that direction, I created the Blackthorn Starter Pack, which is basically a tarball with all the libraries you need plus a little glue to make things work. See the wiki link for more information and downloads.

Escalator

For fun I've been working on Escalator, which is yet another experimental object system for Common Lisp. Escalator is inspired by this blog post on Entity Systems, which are supposedly used in the MMO industry. Escalator is my attempt to provide idiomatic support for Entity Systems in Common Lisp as a high-performance alternative to CLOS.
