Pedro Calvo put together this kickass fan music video of GlaDOS from Portal 2 singing the ending song, “Want You Gone”. It’s really well done, with him having inserted homemade animations into the video to supplement the bits of GlaDOS singing.
It’s also a really damn catchy song. The Portal games are good with that.
Just note that watching the video will spoil the game for you if you’re a fuckin’ loser and haven’t yet played/finished Portal 2. Shame on you!
