Well, this is my newest organic chemistry related model. Twistane is a strange molecule. This model containing many intersecting twistane units looks much stranger, doesn't it? Any suggestions how to synthesize this? ;-)
Update And now, coming with an inner core which can move within its cage (model with two interlocking parts): This is some kind of "berry" which evolved from the Flower Of Twist. Please refer to https://www.shapeways.com/product/GHX9E772C/flower-of-twist-as-a-cage
