    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.

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

I really liked the idea!

u/silver_bear

I guess you beat me to the idea of using monospace, but the seconds are way cooler anyway! :D
u/akm

Haha yeah, just saw your dweet. I didn't even think of using consolas you did though... I could've saved a byte!
