This is called Helicone – and you can find it on Amazon.
These sculptures were made by John Edmark – who also did the spectacular Fibonacci sculptures we showed you a while ago. Edmark is a lecturer in the design program of the Stanford Department of Art & Art History, where he teaches classes in design fundamentals, product design, chair design, paper as a sculptural medium, color, and animation.
Edmark describes these as “instruments that amplify our awareness of the sometimes tenuous relationship between facts and perception.” Here are just a few which I really liked, but you can see many more on his Vimeo page.
