    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.

d/23823 figure 3

u/taupelink

briefly: Y ranges from -2 to 2. Below the middle line, Y is positive and there's more green than average. In the large top and bottom areas, Y is between -1 and 1, and there is more blue than average.
u/taupelink

Note the formula for the top of the rectangle, 540+k/Y. This breaks the window up into four horizontal bands. From top to bottom, they are: -2<Y<-1, -1<Y<0, 1<Y<2, and 0<Y<1 respectively.
u/taupelink

Correction: -1<Y<0 is the top band, -2<Y<-1 the second from the top.
u/taupelink

The green component formula is k+k*Y/2. This is greater than k when Y>0.
u/taupelink

The blue formula is k+k*C(Y*1.57). This is greater than k when C(Y*1.57)>0, i.e., when -1<Y<1.

Looks like a bunch of people looking at something shiny. Maybe they're at a concert? 😁 (I might have a slight touch of covid quarantene symptoms...)

I was going for something more abstract, but that's a nice interpretation!

To u/danny@hille.dk: Not sure whether this is the kind of thing you had in mind. I figure there's no harm in dweeting though :) Thanks.
u/taupelink

In fact, re-reading the rules, I think this dweet is out of contention, since it doesn't create definite shapes. Carry on!
u/danny@hille.dk

I think it's great!
u/taupelink

Thank you! (I guess there are still rectangles, just small ones)
