Turns out that it's fairly simple. The documentation on the code swarm 
wiki [1] is fairly good.

- Install packages ant and sun-java6-jdk (no recommends required)
- Make sure the sun jdk is actually used:
  sudo update-java-alternatives -s java-6-sun
- Get code swarm source:
  $ svn checkout http://codeswarm.googlecode.com/svn/trunk/ codeswarm
  or, if you prefer:
  $ git svn clone http://codeswarm.googlecode.com/svn -T trunk
  $ git gc; git svn show-ignore >> .git/info/exclude
- Build it by running 'ant'
- Get and convert the D-I SVN history as documented on [2]
- Run code swarm with the resulting XML file: ./run.sh ./data/d-i.xml
  the frames will be shown while they are built; some options are
  available (type "?" for help)
- If you want, create the video (see [2]); probably the most complex step;
  debian-multimedia archive is almost a requirement

Attached both Joey's config and my latest config (which has the 
alternative categorization I mentioned yesterday; colors may need some 
more thought) and the awk script I used to strip down the SVN log.

Here's a hack that somewhat mitigates the bug Joey reported [3]; I only 
get the "files are tiny dots and too dark" variant:
