Another dead-end hobby of mine: generative art. I program in c with the Cairo library to make little drawings. I do this some Sunday afternoons instead of tinkering.
Here: testing a new noise function to control the brush. I didn't intend to share it but the result surprised me and since I haven't published anything for a week...
In the long run, I'd like to use this technique in animation to illustrate some video essays.
Because yes, that's the advantage: once a first drawing is done, it's easy to fiddle with some parameters to create very evocative psychedelic animations.
