I've seen the original site where this picture came from. the link to download the map was there, but this was a long time ago, I don't remember what site it was on... I found it while using stumbleupon on my old computer...
Does anyone know the map's name? D:

Looks more like a glitch than a map.

Also wrong board.

it's not a glitch, it's a map.
somebody made a small room with two portals already set  up like that.
I can't find it :(
