Wow! This guy put together a mash-up that rocks!

Unrelated to my classes this semester, I ran into this and recalled back to last spring when this would have been perfect inspiration.  I've seen a few mash-ups with a similar idea, but this one is great too.  There are a few comments on the YouTube page that are somewhat negative, but they address content more than his ability to keep your eyes moving and keep with the beat of the music mash-up that was created by a different artist. I enjoyed this very much and I've seen it three times now already.
