Okay, well not quite a music video(!), but my coauthor Steve Flammia has done a videoabstract for our paper (on quantiki at http://www.quantiki.org/video_abstracts/09050901):
You can dance if you want to.
You can leave your world behind.
Is Steve attempting to grow a handle-bar mustache?
That is a truely epic mustache. Nice paper too.
First, the comment on Steve's mustache: I think he is starting to look like a young version of David Wineland :)
Second, Cesar recently uploaded our own video arxiv summary (inspired by this one!) using high-tech equipment. This abstracts idea is quite fun.
