Portal is a very good, very clever, very heartfelt game, which perhaps explains why the people who love it really, really love it, and create some pretty astounding stuff around it. (And I'm not just talking about these, which I'm 98 percent sure I should put on my rearview mirror.)

Exhibit 1. One of those near-mythical fan movies that doesn't make you embarrassed for all involved—and it makes me wonder how Portal might play if it was an action game. Blasphemy, I know.

Exhibit 2. This is just about the nerdiest/sweetest thing I've ever seen. I don't even have a heart and my heart got all melty.
