US style lever handle set with build in combination! Sweet!

This is an interesting design, I wonder how it works...

This guy puts out some seriously slick designs... but I get the feeling that most of them (Digital Translator, Faucet, etc.) are often more along the lines of models of industrial design concepts, rather than functioning prototypes.

I also wonder how random the shuffling of the numbers is when the handle resets. Computational randomness is difficult enough, I would suspect that the mechanically driven shuffling in this would be at least somewhat predictable. Allowing the potential to derive the numbers either immediately or, worse case, over a couple observations of the handle immediately after access.

Would be interesting to pull this apart and test it out though.

I'm disappointed to hear this is just vapor-ware. But thanks mac for the link to the other designs.

In such a design, the wheels would need to rotate without much friction (otherwise it would be too difficult to use),
so they could also made to return to all 0 when released.
