A friend of mine recently discovered this weird website: http://www.wannabefameass.com/
All it consists of is a countdown and a 12 second video showing a door which is the same door from the 21st Century Breakdown booklet: http://i.imgur.com/vM5IU5F.jpg
If you stop the video at 10 seconds there's a single frame of a gate that someone identified as the gate to Jingletown Studios. The door is probably the door to the studio.
On vimeo the video is titled "#1" so there's probably more to come.
What do you guys think? I think the most interesting thing is the countdown that's counting down to 36 days from now. Something's gonna happen. I have no idea if it has something to do with Green Day though.
