    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.

Spinning gold ring

u/jpthinker

I wanted to shade this, so that the half of the ring further away would be darker, but I couldn’t quite figure it out.
u/lewdev

I tried. I'm not sure if it's very good. d/32457
u/jpthinker

That's just what I was trying to do! I will study that up well. Thanks u/lewdev !

天の川 (the milky way) twinkle

u/jpthinker

I remixed my milky way from two days ago (the actual day of the tanabata star festival!) thanks to advice from u/rodrigo.siqueira to add a t element to the red argument. I also realized I could assign variables to the result of a ternary, instead of assigning within one

天の川 (the milky way) for 七夕 (the star festival)

u/rodrigo.siqueira

Change S(i/2) to S(i/2+t) and the stars will blink, shine and fade
u/jpthinker

Thank you u/rodrigo.siqueira ! I take this as a warm welcome since this was my first dweet! And that's exactly what I was trying to do, before I ran out of steam and fell asleep, lol. I remixed this one with your suggestion and figured out a few spots to golf down the extra characters

You've reached the end.
