Code_swarm video of Xen development

This video uses code_swarm to visualise the development of the Xen project. It shows commits to xen-unstable.hg. Each dot represents a file. New files appear in a random place, and with each commit they get brighter and move towards the person making the change.
The colours represent a fairly arbitrary division of the code into more-or-less equal-sized areas. Feel free to suggest better divisions, and better colour values too.
The names are pulled out of the “Signed-off-by” comments using a small script. Otherwise it looked as though Keir was doing all the work!
I’ve done my best to identify names that appear in more than one form, but there are bound to be ones I’ve missed. There are also a lot of people listed only by email address. Again, corrections are welcome.
