CodeCity

I reported earlier on a port of Mondrian to Squeak Smalltalk allowing you to visualize and analyze your object oriented system.
Maybe you also know the CodeCrawler tool from VisualWorks.

Meanwhile there is a new tool available called "CodeCity" presented at ESUG 2008. It visualizes the code in 3D which is very cool. It's written in Cincom Smalltalk. A paper is available here and the projects page here.

James' blog also has some infos and a nice video. Thanks for making this available!
