Follow the action at this site live (and with debriefs in the days afterward). And you can keep track of the projects using a variety of tools.

If you’re in New York, here’s where to go; you must present valid ID. Bring your own supplies and hack 11-7, or just party 7-9:30! (We have a Wii to play with, even – just in case our projects decide to stop working.)

Where to Follow Along Live
