I’m in
Even though I probably don’t have enough time this week-end, Ludum Dare is something I can’t miss. Well, I haven’t been able to finish a game for at least the last five times, but hey, the past is the past. 
Code/Framework/IDE: Either Haxe + NME with FlashDevelop or JavaScript with my own framework (which is a weird hybrid between a game framework and a web framework) and Aptana Studio 3
Graphics: Blender 2.6 as usual, with some GIMP
Sound/Audio: GarageBand + sfxr + Microphone if needed
Other tools: TexturePacker, ImageOptim
