Malleable Music is a project by Sidney Fels at the Human Communication Technologies Laboratory at the Unversity of British Columbia in Canada:

The malleable surface touch interface combines a deformable input surface and video processing to provide a whole-hand interface that exhibits many attributes of conventional touch interfaces, such as multi-point and pressure sensitivity. This interface also offer passive haptic feedback, which can be effective with applications such as sculpting or massage. (...) This interface allows for people to control the computer using pinching, twisting, squeezing and other forms of whole hand manipulation. We want to use this device to create a new musical instrument.

Video here. Why do I blog this? looking for new interactions that may be interesting to kids future games, I found that capturing touch interaction through a deformable surface is relevant idea.
