This model of impossible coil was created in Autodesk 3ds Max by Makoto Okazaki, who was a student of The University of Tokio. To demonstrate the model he create an animation rolic, in which we see how many separate parts the model contains. This model is more complex than many other models of impossible figure, because it consists of curved lines.

The rolic was found at http://www.autodesk.co.jp/adsk/servlet/item?id=10418054&siteID=1169823 and put to YouTube by me.
