Procedural Art Project
My current main project (in my personal time) is a program I am writing in Python. It generates images based on user input, random numbers, and math.
The first versions were written between August and October 2013 using the Pygame library and generated images at 1000 x 1000 pixels, which I found to be too small.
I rewrote it using Pillow (the Python Imaging Library fork) and Tkinter starting in January 2014, and have been working on it a little at a time since then. I typically generate images at 9000 x 9000 pixels, which is suitable to print at 30" x 30".
