Ideas for an interactive donation box?
I need to create a donation box for a non-profit art center where I volunteer. The box needs to be interactive. That is, inserting a paper bill through an opening in the box, triggers a fun toyetic response, preferably not audible. Maybe something spins, a light flashes, LEDs arranged to spell "Thank you" flash on and off, etc. The box could have four or five different openings, each with its own interactive feature. I love to get ideas from the Instructables community as well as input on toys or electronic devices that can be adapted for this.
