Inflatable hands with moving fingers

This pair of blowup hands are five meters tall and one meter wide at the base. They have been painted to resemble real hands, with cracks in the palms and dirt under the finger nails. They really come to life when they start moving. Each inflatable finger can move in the same way that real fingers do and when all the fingers start to bend and flex in time the effect is quite uncanny

See the video to get a real idea of the movement.(quicktime needed)
