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

https://fig.sonnet.io

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.

Well done!

This is a cool way to teach!

I was blown away by the little functions at first and I too made a clone to experiment with calculang [1].

I added an evaluation feature (F9) so you can select sub-expressions and see what they do, which was helpful to figure out some patterns (video in [2])

Reminds me of [Replicube](https://store.steampowered.com/app/3401490/Replicube/), which has released recently and does the same kind of thing in 3D.

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

Cool stuff.

Learned by scrolling far enough right in view source: The last line is editable and eval'd.

Request to author: keep the newlines.

Love it, simple & cool :)

Would be cool to implement this physically as an array of iris diaphragms

I’m considering that as a load screen animation. Bunch of different functions, and the user will be entertained.

I love it! Here's a windscreen wiper.
