Be sure to visit the California Lightworks booth (I assume that they'll be there again?) and say hi to the staff.
I went to this 2 years ago and it was a lot of fun so, if I don't have surgery before then, I think I'll go on Sunday, when it's open to the general public.
Anyone else going?

EDIT:
Now they want $10 at the door for the public to get in. Screw that...
