I invented and built these BUBBLES for the Alice Farley Dance Theatre production of "Black Water" at La Mama Theatre in New York City back in the early 90's.
The audience reaction to them was so strong that I shrunk them to about 8" in diameter and created a product ORBITON which had the illusion of a bubble floating in mid air in a clear cube. This invention was licensed, manufactured and sold by Andrew Lloyd Webber's Really Useful Games Company.
* Note that the striations that appear in the video are a result of video frame speed and are not visible when viewing in person, where they appear as a solid, transparent bubble.
