The Codebits event is awesome. The haven't had this much fun in a long time.
You can look through some great pictures of the event at Delfim's gallery.
The F.E.V.E.R. concert last night was pretty cool, although I'm not a fan of their kind of music. Even through out the concert people where still coding like good geeks.
Update: uploaded some pictures of my own to Flickr.
