I have just uploaded a video of some of the Flash 10 Year Anniversary party from last night (held at Adobe / former Macromedia HQ in San Francisco).
The clip includes birthday wishes from Strongbad, and Nectarine and some comments from Kevin Lynch and the guys from Big Spaceship.
You can view the complete video here.
Highlights of the night included a birthday greeting for Flash from Strong bad, Flashtinis, and Halo into the night.
You can find more info on the anniversary and history of Flash here.
Sorry about the crappy quality.
