Found this cool visualizer named
Gource that lets you visualize SVN commits.
It's not quite as exciting as I thought to watch Darwinbots3 grow, but it's still pretty cool. I've attached the SVN log for DB3. Just download Gource and run it with this command line:
gource --max-files 10000 --auto-skip-seconds 1 --file-idle-time 99999 --log-format custom darwinbots.txt
