I just thought about turning a rubik cube into an interface or lock by using 6 encoders as a way to grab the rotation and send those inputs to an rgb 3x3x3 cube or 8x8x8 rgb locomatrix, when ready ;) I'm still sidetracked by my continuum quantum device prop build, repairing and upgrading my printrbot simple and work of course but always try to come up how to integrate functions and interfaces into props and things laying around. 

Googe found me this:

Ha, and this, so I'm not the first - good!
