Schrödinger's Clock

The app illustrates some of the basic principles of quantum mechanics through an invention known as Schrödinger’s Clock™. The app is purely illustrative of one principle and uses the camera built into your device; as such, it is both educational and amusing.

The accompanying website (link provided in the app) provides more detail about the Clock, its purpose, the different variants and how they work, and some introductory references to quantum mechanics, among other topics.
