u/jpthinker

Reading through the code, this is so clever! I like how you combined the black background fillrect with the i variable's initialization, and how you used clearRect to get away without doing any fillStyles.

Where did you get all your inspirations and algos from? ;-)
u/rodrigo.siqueira

The "infinity" symbol is just the graph of: X=sin(i/2) , Y=sin(i). A particular case of #Lissajous curve. I then introduced some noise and interference It emerged as a remix of previous posts.
