I'm currently at SIGGRAPH in L.A. The most significant event so far was the Fast-Forward session (each paper presenter is given 50 seconds to advertise the paper's awesomeness). Highlights include:

Topless presenters: 1 (male)
Raps: 2
Ninjas: 1
Guys in drag: 1 (see ninja, above).

In related news, I'll be in Vancouver on Friday.
