David O'Toole has announced the 2010 International Lisp Games Expo:
The 2010 ILGE is month-long exploration of programming and playing games in Lisp. This "virtual conference expo" is relatively free-form and self-assembling, something like the community it serves.
All entries must be playable games written in some dialect of Lisp (Common Lisp, Scheme, Arc, Clojure, et cetera.) Multi-platform release is encouraged, but not required.
