The musical score is whimsical and almost as funny as the game itself. Grab this one, but you need a sound card to really enjoy it. Most file browsers on any operating system present the file system as a series of 'folders' or as a tree. The wonderful time-waster xcruise comes to the rescue. In xcruise , the entire file system is visualized as a universe.
Directories are galaxies within the universe, and files are stars within a galaxy.
You can fly around the universe using the mouse. The feeling of 3D motion is quite exhilarating. In xcruise , the colours of galaxies and stars are determined by their names. The radius of a star is proportional to the cube root of the file size, so the 'mass' of the star seems linearly-related to the file size. Most amazingly, symbolic links are represented by green 'worm-holes' shooting from one star to another, possibly traversing several levels of galaxy.
