The Ejs Strange Harmonic Oscillator model displays the motion of two masses connected by
A massless rigid rod and the masses may move without friction along two perpendicular rails in A horizontal table.
The energy of the oscillator system can be changed via a slider.

I added some more GUI elements.
In the simulation $x(t)=R*sin(\omega*t), y(t)=R*cos(\omega*t)$
If you un-check the check box for info, it will back to the original view.
