A simple 16x16 dot animation from simple math rules

I made a drawing app with programmable brushes inspired by tixy:

It’s pretty fun because the shape dynamics are time, and not pressure/tilt based, so you need to draw in a rhythm.

Here’s how they work and how they’re implemented:

I loved tixy when I first discovered it a few years ago so created this https://www.mathsuniverse.com/tixy (with permission from the original author) with puzzles to solve on the tixy grid. I use it with my computer science students who get really into it.

The classic: sin(x/2+t)+cos(y/2+sin(t))

Love it, simple & cool :)
