Animated Lissajous figures

M= N= delay

This animation is based on HTML5 + JavaScript and unfortunately doesn't work in InternetExplorer yet.

Equations for the curves are
    x(t) = Sin(Mt)
    y(t) = Sin(Nt + Fi)

where M, N are integer frequences and Fi is the phase difference. If N has a small "add on" then there is phase precession (i.e. every "new" figure has a new shifted phase).

This animation is based on HTML5 + JavaScript. Java based (need Java plugin) animation.
