fsm (from SGI---you can see it in action in the movie "Jurassic Park") was an interesting filesystem viewer. It presented the filesystem in 3D on an infinite plane. Directories were squat boxes, while files were tall and skinny boxes sitting on directories. The size of the boxes reflected the size of the directory/file (huge files literally stood out). Color was used to indicate age---the older the file, the cooler and darker the color.
