Draw with code - touchdesigner

Hello everyone!

I’ve been using touchdesigner for a while now but I already love it.

I really like the works of the artist Aaron Alden and I would like to ask you for advice.

I would like to create a project inspired by Aaron Alden.

I would like to understand how to draw with code, starting from numeric variables to generate visual shapes.

If you can recommend me some tutorials or courses to follow I would be grateful.

Thanks!
