It doesn't always have to be an app.

A young designer from Eindhoven has created these beautiful toys to be used in hospitals to explain procedures to children. His toys contain the 4 most commonly used pieces of medical equipment: X-ray, CT-scan, ECG and an echocardiograph. Each machine has light and sound so the kids get a pretty good idea of what is going to happen to them. Now all he needs is a business angel to finance him. (copyright Hikaru Imamura, Fast Company)
