Groups of Parabolas

You can see two groups of parabolas (y = .015 x2) moved in parallel. Please mouse click on the deck image and move it (drag and drop). 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.
