Sandro del Prete

The invention of the wheel was one of mankind's greatest achievements. Since then, countless types of wheel have been developed. So I decided to join the ranks of brilliant wheel inventors. It took me a great deal of thinking and drawing, but then I'd got it: I had designed my own wheel - a wheel the world had not set eyes on before. This six-edged square wheel, seen from the side when not in motion, does in fact look like a square. On turning the crank, however, it changes into a circular disk, which again changes into a hexagon.
