Hi,
Actually, I meant P5 in Python 
. I am okay with python but donāt know much about javascript (unfortunately). However, now I am trying to learn āoriginal Processingā through these videos, which are nice but a bit slow:
OpenProcessing looks amazing! Thank you for suggesting that. However, I have a few ideas that I am not sure I can find more easily than I can implement them (mainly because I donāt know the right keywords 
).
What I have in mind is similar to this (Flocking / Examples / Processing.org) but not quite the same. But the Boid function is pretty complex at first glance.
Iād like to see your works if you share them somewhere publicly and donāt mind sharing:)
Thanks for your response.
