I have made some modifications to my cube experiment so I thought I’d share them.  In this version I have added Z support for the random position of cubes, as well as the “Chatoic” rotations and movements.  Using any of the normal rotate functions you will get a single rotation in Y, using a chaotic rotation will give you rotation on all 3 axies.  Of course the source is available for the taking.
