Blame It On The Bike!
YouTube video by Dave Pagurek

The Ontario Government is trying to strip out bike lanes we just got finished building and is adding lots of red tape to the process of adding new bike lanes. I got annoyed enough that I wrote, recorded, and animated this protest song in a week. Go call Doug Ford!! youtu.be/Z9vsHzj_-ZU
#genuary 20: one line. Split the light beam into its components! The secret is... this is actually many lines, rendered via p5.strands instancing, but they come together to make one line. openprocessing.org/sketch/2851676 #p5js #p5v2

#genuary 19: 16x16. Reminded me of the size of ASCII tables. Paired that with p5.strands shaders to bubble around the mouse + add chromatic aberration. openprocessing.org/sketch/2851072 #p5js #p5v2

#genuary 17: wallpaper. A recreation of an old but great one. Not a complicated pattern, but was fun to recreate bevel by adding a blur and then using the brightness as a height map. openprocessing.org/sketch/2850098 #p5js #p5v2

In addition to helping maintain p5.js, for my day job, I make a motion graphics video editor, Butter. I think the best way to do that is have every component be a creative code sketch, so we've been building an editor for developers to create components out of regular p5.js sketches. A thread:

#genuary 9: crazy automaton. This is kind of reaction diffusiony, where a pixel lives or dies based on its neighbours in the previous frame, but operating on a warped domain. Implemented as a p5.strands shader! openprocessing.org/sketch/2843293 #p5v2 #p5

If you use Processing in any way, we’d love your input. It helps us understand what works and what needs attention.
