WHAT IS IT?

BORG CUBE! No really, it's a maze generator and traverser, in three dimensions.

THINGS TO NOTICE

Using the observer and sexyz and set-gaze-xyz, it is possible to create moving camera effects. In this model, the camera is flown about the model space, giving the illusion that the cube is rotating.
