I’ll probably add to the list as I go, but:

Tools:

Vim, Chrome Developer Tools, Firebug, bfxr, audacity, ASE

Libraries:

Box2dWeb, Three.js, d3js, underscorejs, <possibly> knockoutjs

I’m planning to go for the solo competition, if I decide to switch to the jam and get help it’ll be from my sound designer friend.  Here are some tools I think he uses:

FruityLoops, Native instruments VSTs (Massive, FM8, etc.)

Good luck everyone!
