For those that are interested, Valve signed and donated a Portal Gun (which I soooo want to keep) for us to auction off for Child's Play Charity. 100% of the auction goes to the charity, so if you're looking for an additional excuse to get this, there you go.
There's about a day left on the auction, so get on it if you want it.
Good luck!
