Laser cut Puzzle box in 4mm ply

This is a puzzle box. To open it you need to perform a certain gesture and press a button. Here is a video: http://www.youtube.com/watch?feature=player_embedded&v=HTdaDZDc90g

Someone who doesn't know how to open it will struggle for a long time, especially if you give them no clues. Once you've learnt the gesture, you can open the box in a couple of seconds.

The gesture is defined by the shape of an internal ball bearing maze. This can be easily changed to customise your box.

Many thank
