Recently I learned about a free software called Processing.
It is a way to learn coding as well as creating designs, etc.
On the Processing Webpage it says:
“Processing is a flexible software sketchbook and a language for learning how to code within the context of the visual arts. Since 2001, Processing has promoted software literacy within the visual arts and visual literacy within technology.
There are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning and prototyping.
» Free to download and open source
» Interactive programs with 2D, 3D or PDF output
» OpenGL integration for accelerated 2D and 3D
» For GNU/Linux, Mac OS X, and Windows
» Over 100 libraries extend the core software”
Here is the third Image I created with this Software
The Processing Website has lots of tutorials and resources to learn how to use this software.
