Discussion on: May 1st, 2020: What did you learn this week?

This week I learned something about noise generation to create something like this

I learned and implemented quad tree instead of spatial hashing but I still don't know what algorithm has the best performance.

I learned about canvas and retina/HiDPI screen, not from zero but I improved my knowledge.

I created other cool feature for particles, not really new things learned, but at least it was the first time for me to do these things
