    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.

Trying to mess around with localStorage

u/TorusField

Uncompressed: x.font="80px MS" d=new Date().toTimeString() l=localStorage b=l.getItem("t") h=100 if(b==null){l.setItem("t",d);x.fillText(d,h,h)}else{x.fillText(b,h,h)}
u/danny@hille.dk

or you could do somthing like this: x.font=2cm' x.fillText((l=localStorage).t=l.t||Date()+'',99,99)
u/danny@hille.dk

ups forgot that backticks is translate to codeblock x.font="2cm'"
u/TorusField

Thanks for the tip, I'm very new to code golfing

u/recursive

Direct pixel manipulation. Interesting approach but it looks like it might always be larger. Does this have a dweeting application?
u/hypothete

I'm not sure. I put this one together in case people had ideas on how to shrink it.
u/veubeke

@hypothete new ImageData(W,H) saves some bytes as does incrementing i by 1 instead of 4 and calculating image data size manually. https://www.dwitter.net/d/2069
