I am reviewing xcruise version 0.24.
Galaxies represent directories, planets represent files, and wormholes represent symlinks.
Planet size is determined by the file size. This is a cool program and it shows lots of opportunity for additional features. A very entertaining program that has potential for actual utility. The only thing worse was an old episode of Superman, where he was frozen far below absolute zero, but was walking around. One option that would be nice to add would be an auto version that would surf your file system or an area that you define and be a screen saver.
