Very well organized event. It was a good chance to talk to Google people and other developers that are interested in latest technologies from Google.

Talks about html5 were very tight to Google products and are not that well supported by other vendors. Several talks were done by Berlin universities people. Those were somewhat boring and abstract.
Anyhow, here are some photos:
