I built a Portal 2 Test Chamber

I have been playing around with the Portal 2 level editor and it is very good for easy level building. The best test chambers on there at the moment seems to be by CaretCaret, but he has used Hammer (the big boys level editor) and I suspect the most popular levels will always be the ones built with Hammer, but I am still liking the in game editor. Here Is My Level, it took me a couple of hours and isn't amazing, but I think it is reasonable.

Non-Euclidean Level Design

Not the first game demo or game to show this kind of impossible level design, but a fun demo anyway.
