Hello,
expert in Python and Processing here. I can implement 1, 2 or 4 for you. My current bid is for for 1 - construct a 2D animation in Processing.
If you want more than one code from 1, 2 or 4, for example if you want 1 and 4, we will discuss the extra cost.
Thanks and let me know if you are interested to work with me,
Paul
