He puts a white sheet of paper on a curious instrument -- Observe carefully what he draws....

The Cycloid Drawing Machine is a complicated but very interesting and entertaining machine invented by Joe Freedman, used to produce magnificent geometric designs based on curved lines. By changing the position of the elements that compose it, the shape of the final design undergoes a transformation!

Therefore, since the combinations of the positions are virtually infinite, you can say that the machine is capable of creating an endless series of completely different shapes, figures, and designs. You will be easily mesmerized by it from the first moment the box is opened!
