First T-Shirt firing: no one injured!

We just did the first t-shirt toss contestant. This was the team
from VisiComp that did a nitrogen powered cannon. A seriously out
of control mechanism. Quite capable of hitting the far back wall of
the hall. In one of life's little techno-tragedies, the battery in
my camera died just before the cannon firing. This is a photo of
the cannon with its nitrogen cannister a couple of weeks ago, just
after it was built.
