I have a confession, I haven't played Portal. It's not that I have anything against it, I just don't have an X-Box that's not buried in Flaming Hot Cheetos wrappers in one of my boys' rooms. I watched my son play a bit though, and I have the soundtrack, does that count? (nerd cred -2, damn). Lego Junkie drops the mic with this, his 14th and final MOC for Iron Builder, and it's awesome.
