XCruiser (formerly known as XCruise) is a filesystem visualization
utility which compares a filesystem to a 3D-formed universe and allows
you to "cruise" within it. It constructs a universe from directory
trees, and you can navigate with a mouse.

The code was almost entirely rewritten and now features Xt support, easy customization of button bindings, colors, and accelerators, keyboard support, and a new rendering algorithm (still incomplete). The monochrome mode was removed.
