I had the opportunity to attend the DEMO party in San Francisco a few days ago. It was an outstanding event that was over the top (in a good way). They went with an Austin Powers theme and did not hold back with the decorations, staff and extras. Here are a few pictures from the event:
(At the entrance to the event, there was a fog machine posted over the doorway with the DEMO logo shooting against it. To get in, you walked through the fog)
(There were quite a few companies showing up their new products)
