Sometimes I get to write about truly awesome things, like this music video which uses the song E=MC² by Ayreon. The song, paired with Portal 2 video clips, is from the album 01011001 (that translates to y in case you were wondering) and tells quite the sad story.
If you've played to the end of Portal 2, then this music video is even more interesting as certain utterances (a direct nod to the multi-player mode) go quite well with the lyrics. The song itself is interesting, but the addition of some Portal clips make it even better. Because portal guns make everything better.
