    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.

A cool effect I found somewhere (slightly modified from https://js1k.com/2017-magic/demo/2894 )

My first Dweet! It's nothing too special, but I did as much golfing as I knew how to do.

u/katkip

Nice.

It is possible to compress about 10% more with small goof tricks. 103 characters instead of 115: P=t*60;P<1?c.width^=a=b=[1]:0;for(i=a.length;i--;)p=a[i],x.fillRect(960-P/2+i,P,p,p),b[i+1]^=p,b[i]=0^p

Slow-render only because I don't know how to golf it enough...
u/Undefined

Post on discord and we'll try to golf for you :P
u/JWinslow23

Well, I'm not sure how to golf this further. Most of the real-estate is in the specific values that make the fern work, which I can't encode in a byte-saving way
