    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.

Bezier Sunset Gradient - Fixed

u/LimeLaser

This version has a proper cubic Bezier evaluation function (w) and uses a non-linear ramping for u and t.

#messy #rainbow

u/DaSpider

Somehow the compressed tweet shows as longer than the uncompressed code, and oth exceed 140 characters?! 😕
u/f8f82804

There's a mismatch in the way that characters are counted -- this compressor uses 32-bit characters which are counted as 2 bytes in the front end, but are counted as 1 by the back end. I think there's an issue on the Dwitter GitHub where u/lionleaf has some comments about why.

Had this laying around. Demonstrates the #illusion in d/15823. The triangle's #gradient remains unchanged.

u/DataMeta

The center of the base of the triangle doesn't exhibit the illusion strongly since there is a constant reference color near it and it is far from the changing background.

Illusory gradient grayscale ("Simultaneous Contrast Illusion"). The bar in the middle is a CONSTANT SHADE of gray. Viewing two colors at the same time influences both of their appearances. #gradient #illusion
