In Total Agreement!!!
A fantastic program which is amazingly easy to use. I love the way symlinked files are actually physically linked together - take a look at /usr/lib! It would be great if the "planets" could be selected for some form of file management (view properties, rename, delete, etc...) perhaps with some kind of aircraft style targeting system:-)
This is a great little program which shows off the power of OpenGL and shows that stuff you see on sci-fi films can make it into the real world. One to impress your friends with!!!
