All results come straight from the Youtube API using "location=!" (iirc) parameters to only return geotagged videos.

Since geotagging isn't used that much on YouTube, a lot of "good results" don't appear. Nonetheless, here are some searches that give good mapping: - occupy movement - deamdau5 live (not all "artist + live" combo work well) - parkour - startupweekend (I just love these events) - hackathon

Have fun =)
