Is this place for real?  It is, at the new Royal London Hospital:

‘Woodland Wiggle’ is a pioneering interactive game displayed on a television the size of a room. It allows children to enter into a storybook illustrated world enabling them to paint; play music; and trigger sun, rain, snow and rainbows with animated animal characters across a number of woodland scenes.

O’Shea used the latest creative technologies, including custom software written in C++ using open Frameworks and an Xbox Kinect camera, to bring the unimaginable to life by reflecting the children’s video image within the scene in real-time, allowing them escape the reality of their daily treatment and interact with the exciting animated environment.
