This isn't music but it was so confusing i had to share...

Ah man the Unreal Chambers, I remember just coming across them while playing the top community maps list Definitely the most insane and creative chambers I've run into, It's still crazy to me how they can flip gravity so arbitrarily like that, I wasn't aware source could so casually do that kind of thing. And of course the map looping and loading more stuff into the same room you were just in the moment you walk around a corner is also frickin' mind bogglin' Man, I might have to get back into portal custom maps just to play more stuff like this again...
