Tonight after the Crunchies is an after-party taking place at City Hall in San Francisco. Staff members of TechCrunch will be there with a couple of iPhone/iPod touches to accept donations on behalf of UCSF Foundation using Square, the new startup founded by Twitter creator Jack Dorsey.

These donations are of course voluntary, but we’re suggesting you give $20 if you’re choose to donate to the cause. If you don’t want to donate, feel free to to just stop by and check out Square — it’s quite impressive in action.

Hope to see you there.
