Inflatable electric tubes

We have two inflatable electric tube installations measuring over eleven meters high (see diagram below for exact dimensions). They are made of white inflatable balls with thirteen moving pipes attached, these pipes are continuously moving, blowing up and collapsing. A powerful light has been placed in the central sphere and is caught by the pipes as they move emphasizing the movement. These are very dynamic objects.
