The ThinkingWithPortals Map Showcasing Thread
I can't make a copy of the water texture and change it. It's just not up my alley. I understand that you and other people tried to help me figure it out on that other topic, but I just couldn't do it. The 2nd map is released if your interested in it anyway.

Looks like a fun idea!
I remember there was some other game (a medieval-themed Doom derivative; blanking on the name at the moment) where you would go back in time and the things you did there would have an effect on your original timeline.
Are you going to have the timelines overlap so players can kill themselves from the future? 
EDIT:
argh... note to self: read first, post later
Other Portal 2 maps: Medusa Glare
Portal 1 maps: Try Anything Twice | Manic Mechanic
I have a thread on Time Travel. If you want more info about it check there. I may post more pictures here later. Still working through a few knots.
Edit: Map is almost done. Working on the best Easter Egg ever and the time machine fizzler.

if you could do your water properly so its not all, square-y. That would be fantablous.

"Oh, in case you got covered in that repulsion gel, here's some advice the lab boys gave me: DO NOT get covered in the repulsion gel."
Would appreciate some feedback if it could look more old aperture-y.
