Even if you haven't played Valve's excellent puzzle shooter, you've probably run into characters from the Portal universe somewhere, whether it be a homicidal robo-ball or an irresistibly adorable cube. Portal's zany cast makes for some good video gamin', and awesome gifts to boot.

I don't typically make knee-jerk purchases. I'm decidedly fussy about what I spend my money on, even. Despite all my hard-coded resistance to this kind of stuff, I'm still pretty sure I'll have a pair of Portal bookends before long, not to mention a plush turret for a certain niece I'm sweet on.

You can see a rundown of what's new from ThinkGeek and Valve in the gallery below, and check out all the Portal goodies from ThinkGeek here.
