Simulation of real combination lock.

Controls:
Up/Down: attempt to open 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.

I made this because my last locking mechanism was so popular. The code is just 0000.

To change the code:
1. Delete or move the big cover group.
2. Set numbers to what you want the code to be.
3. Pause.
4. Rotate all the green decagons so that the cut circle looks to the right, the circles on the vertices of the decagons should be inside the purple triangles.
5. Unpause and your done.

While making this I discovered a performance window pops down when you hit Numpad *.

(Kudos to anyone who can find where I got the four starting digits.)
