What is Lissajous Curve?

In mathematics, a Lissajous curve, also known as Lissajous figure or Bowditch curve, is the graph of a system of parametric equations which describe complex harmonic motion. ----Wikipedia

For more infomation, see wiki.

Draw the Lissajous curve corresponding to the given A1, ω1, A2, ω2, φ, where x = A1 * cos(ω1 * t + φ) and y = A2 * cos(ω2 * t).

Note that A1 and A2 are constant, and φ is changing automatically.

• Use arrows or WASD to increase/decrease ω.
• Press space or click left button to pause/continue.
• Scroll the mouse wheel to speed up/down.

Enjoy :)
