Can someone please post any example of JavaScript code to "toggle the 
states" like in either http://www.math.muni.cz/~plch/nkpm/nradanm6.pdf 
or https://www.pragma-pod.com/present/talks/fifteen.pdf?

I produced the graphics as explained in the section 13.6 of the metafun 
manual, but I would like to press the button only once at the beginning 
of the animation instead of twenty times.

Thank you very much,
