w-h-i-t-e-v-o-i-d is developing some really cool software to project video images on physical objects.

(from whitevoid) “Video objects” is a software able to perspectively distort video content in realtime. The pre-distorted videos are projected from one video projector onto multiple real world three-dimensional objects. The resulting projected imagery appears to adhere to the surfaces of the objects. The objects can have virtually any shape and and can be arranged in a variety of angles.
