    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.

Wow! That's trippy and cool looking :D Looks like an oil spill or something #plasma #oil #oil_spill
u/joeytwiddle

Great!
u/tomxor

Neat, looks like #diffraction and #Interference, I guess it is litterally the later.
u/katkip

cool
u/Purpzie

Still seems to look the same without s.backgroundBlendMode='difference'
u/yonatan

Dwitter doesn't reset CSS styles when you edit the code. Try making it '' instead of 'difference'
u/lionleaf

u/yonatan Oh, I guess that's a bug.
u/DataMeta

Absolutely incredible

Shortened by a whopping 55 characters

inspired by @Purpzie #interference i simplified an old one ... what fascinates me is the entire pattern is based on modulo function applied to Quadrance, there is no cosine, sine, trig, or even really commands to draw colors based on posiiton. #waitforit
u/donbright

sorry meant to post that on my remix
u/Purpzie

oh pfft it's okay
