At Easterhegg last weekend I was introduced to this amazing lock (Master Lock 1500iD).
You can enter a combination of up, left, right and down -movements of ANY LENGTH to be your code.
This mechanism is basically a mechanical hash-function of the movements you do.
This is a simplified demonstration-model to illustrate the code-mechanics.
It contains neither the actual locking nor the reset-mechanism nor the mechanism to set your own combination.
I just finished the design and did not print it yet. But I made sure it is printable.
