Bought Portal 2 yesterday thinking it would work on my newly upgraded computer. It didn't. Installed it on brother's laptop. It worked. Gave game to brother and replayed it on his computer. Good times were had.
Anyways, I noticed the computers in the labs had desktops similar to the one used as the backdrop for the ending song. Recreated it as a dekstop for my computer. Yep.
Free to use and whatever. But if you post it on any other websites give me credit for the recreation. That is all.
