Park(ing) Day 2012

what are people doing for Park(ing) Day this year? Any fun things going on in the Bridgeport/Pilsen area? I'm a member of ssh:chicago, the new hackerspace/makerspace starting up on the South Side. (http://sshchicago.org/) We're a creative, fun bunch, and we're looking for partners in crime for that day. We can add various geeky workshops to your Park--throwies, Nerf gun hacking, maybe a fun soldering demo... anyone interested?
