Welcome to Interactive Playpen 2008! We'll be fiddling with the site a bit more to make sure everything is working. Please leave feedback here if you notice anything strange.

This year we've got a fresh batch of Legos and a new twist: if you'd like a little competition, tag your photos to submit your entry into one of our 10 categories. Once the conference is over we'll choose winners based on community feedback. OMG, FREE T-SHIRTS.

Can anyone think of other categories we should include this year? We want to get people building and collaborating.
