interactive video projection on a floor or wall. A white wave spreads over the red floor. When you step onto the floor you can break the wave with you shadow. By breaking the wave in the right way you can make amazing spirals.
Spiral waves is a simulation of a system that can be found a lot in nature: an excitable medium. An excitable medium is a system in which a wave can propagate, but after the wave has passed a certain amount of time is neede before a new wave can pass. An impulse above a certain threshold triggers a wave of activity through the excitable medium. In this simulation yoiu can break the wave by moving and start it by lighting a lighter.
