The Fun Theory

How do we get people to go outside and walk even though it's dark and cold? What you need is light and joy, and we could achieve this by making a game and sound machine. Pressing the button starts a game where you have to put out as many lights as possible along a given path. The lamps are in the ground and are put out when someone stands on them. Whoever puts out most lights wins! Submitted by Maja Petersson
