I really like this song. It's bouncy. And the color transitions keep time with the music pretty well (except for that little part at the end where the music cuts off for a few seconds, but what can you do).
Perhaps I'm an idiot for asking, but how exactly does one get these skins? I have a Companion Cube Hat, but that's about it.
Those...aren't cool. At all. It looks like someone dismantled construction equipment and stuck the random pieces on Atlas and P-body. I remember seeing the roll cages in one of the trailers...but I didn't actually think they'd use them.
