There it is! my first [sharing] on this forum. ;)
It's a patch made with phys objects
that records a position of each element of the pendulum
and draws it as white pixels on a three videoplanes;
You can move a pendulum with jit.phys.picker or with @motorvelocity parameter controlling one of the jit.gl.hinges
Simple but kinda nice so I thought I post it...
Maybe someone find a way to do something cool with it.
