Barry Martin's Hopalong Orbits Visualizer - Created using three.js and vrrenderer.js

[Up-Down] Control speed - [Left-Right] Control rotation

[Up-Down] Control speed - [Left-Right] Control rotation

These orbits are generated iterating this simple algorithm:

(x, y) -> (y - sign(x)*sqrt(abs(b*x - c)), a -x )

where a, b, c are random parameters. This is known as the 'Hopalong Attractor'.
