This example is a porting to RapydScript
of 'Growing circles' published on http://jcscript.com/
See how easy it is to use Javscript libraries, here "jCanvaScript"
And if you don't know how to translate to RapydScript
just use inline Javascript.
More info on RapydScript : http://pyjeon.pythonanywhere.com/rapydscript

For now the code can not be saved.
You can contact me to gmail.com using salvatore.didio,

Please, be patient while compiling

You can modify the code and press 'Start'
