Groups of Parabolas

You can see two groups of parabolas y(x) = .01 x2 − x moved in parallel. Please mouse click on the deck image and move it (drag and drop / touch and move). Turn rotation on and off as you like. I hope you will enjoy the typical hyperbolic and elliptical moirés.

The number field permits one group of parabolas to be decreased or increased in size.
