When doing arts and crafts people spend thousands of dollars on rubber stamps. What if they bought one rubber stamp that could change into any shape or image they wanted? You know those novelty gifts with all the pins that you can put your hand under and the pressure makes the shape of your hand or whatever you put under it. I was thinking using something like that with pins, but you stretch a piece of rubber across it. The computer sends a signal to the pins that push the right pins out to make a shape. The shapes would be infinite.
I have no idea how the pins stay out - maybe electro magnets turned on or off.
