    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Lorenz Attractor in color - this will be printed and framed. #lorenz #attractor

u/katkip

you really like #chaos math and attractors
u/taupelink

With good reason, I think :) They are beautiful and, well, strange
u/KilledByAPixel

You should frame the code along with the image ;) Awesome work.
u/rodrigo.siqueira

The prints are ready! Yes, source code is printed with images. https://twitter.com/rsiqueira/status/1143629…
