Algodoo

An upgraded version of my original combination lock.

Same controls and starting code of 0000. The main difference here is that you can set a code by simply moving the number wheels when the device is unlocked.

Controls:
Up/Down: attempt to open or close lock.
Numpad 8/9: move left number wheel.
Numpad 5/6: move left middle number wheel.
Numpad 2/3: move right middle number wheel.
Numpad 0/.: move right number wheel.

To change the controls just modify the big red hinges.
