sketch-a-day
coding a visual idea a day
Welcome! My name is Alexandre Villares and since January, 2018 I have been coding sketches everyday, publishing the source code in the same repository that stores this page, github.com/villares/sketch-a-day.
The results here are mostly tentative, exploratory, and I don’t feel like they need to be relevant or meaningful on any particular day. The everyday practice leads to the emergence of ideas that I consider interesting, worthy of further exploration. Some of those have been added to selected work, this collection itself became valuable for me, and it is my pleasure to share it with anyone willing to explore coding as a creative and expressive medium.
You can follow me on Mastodon @villares@ciberlandia.pt or at @villares@pynews.com.br, where I post most of my daily sketches. Please do not hesitate to contact me regarding licenses to use my work, teaching opportunities, consulting or other projects.
If you appreciate what I have been doing, you may also support my artistic work, research and open educational resources I publish on-line using the Brazilan PIX key at 46c37783-5edb-4f1c-b3a8-1309db11488c, PayPal or gumroad.com/villares, where you can subscribe to my [sketch-mail] newsletter.
Here are listed some of the tools I have been using:
- [py5] A new Processing Java + Python 3 amazing tool
- [pyp5js] initially a Python to p5js trancriptor, now a pyodide + p5js tool
- [pyscript] A new Python in the browser tool.
- [Py.Processing] Processing Python mode
- [Processing Java Processing Java or “standard” mode
- [p5.js] JavaScript library from the Processing Foundation
- [shoebot] Generate 2D vector graphics with Python
- [FreeCAD] A wonderful 3D modeling tool, CAD & more, Python infused.
- [p5py] A Python 3 implementation of Processing ideas (no Java needed)
- [flat] A generative infrastructure library for Python (via Allison Parrish’s Bezmerizing)
- [VPython] Python + glowscript gives you 3D on the browser
- [PySimpleGUI] Python GUIs for Humans

Back to drawing text with colors for highlights. I have an earlier sketch that uses Python’s tokenize to draw source with some basic syntax coloring https://github.com/villares/sketch-a-day/tree/main/2023/sketch_2023_08_14, this one is simpler (preparing for another idea).

All the 125 possible not self-intersecting polygons form a 3 x 3 grid of points (without rotations and translations).
sketch_2024_04_16
Success! All the possible simple quadrilaterals from a 3 x 3 grid of points. Yesterday I had broken my hashing function that made it possible to eliminate rotations (it is possible to eliminate reflections too, but I like to have them)
sketch_2024_04_15
still WIP, my translation/rotation elimination strategy didn’t work (so turned it off on this output)
