I chanced upon this design by David Granath recently. His design task during a 2-day workshop with IDEO was to identify a behaviourial problem connected to food and from that design a product. The objective is not to solve the problem (not that he could) but to bring light on the behaviour itself. The behaviour he picked was the battle between parent and child, where the parent try to control the child through the food and the child is testing boundries by refusing.
