There will be a hackathon on Saturday, 9-10am (through the afternoon I think), located in downtown Minneapolis:

It will be a place to hack on anything civic related, government, public participation, etc. And maybe more importantly, to meet people in the area interested in such things, for future collaboration. I'll be there, so there'll be some Python hacking going on to be sure.
