This looks very cool. With Creole you can explore your Java code visually allowing you to see its structure and the links (calls, accesses, etc) between its different pieces. Its based on SHriMP which is a generalized visualizer for hirarchical information.

Its well worth checking out the demos of both.

The drawback is that Creole won't work with Java 1.4.2 on Linux. Seems to have something to do with the way eclipse interates swing components into SWT.
