    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    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.

yeah its like a city with spotlights shining into the sky, mirrored in water,.... or maybe like a gigantic hallway with really shiny floors and white ceilings with spires coming down to the floor as support

#circlechallenge No trig, no direct square root: Just using the Pythagorean theorem + the fact that sums of odd numbers give perfect squares

As part of #circlechallenge I go back to the old rational parametrization of the circle from Wildberger's "chromogeometry", which has elements of Euclid. Each frame draws rational points on a circle, and each frame the radius gets bigger. All of the patterns are a kind of optical illusion.

u/donbright

changing '2' and '3' to different numbers will give different patterns
