    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.

I tried to make the code to 140b. I couldn't so I figured out to give it to do it

t<1?s='\n':b='Backspace' e='Enter' x.reset() onkeydown=k=>{o=k.key;l=o.length<2|o==b|o==e?k.key.replace(e,'\n'):'';l!=b?s+=l:s=s.slice(0,-1)} x.font='2cm a' h=s.split('\n') for(i=h.length;i--;)x.fillText(h[i],0,60*i)

the code I posted is like a text editor. Maybe someone of you watching this can make it run! Congratulations to the one who does it (if possible)

Its binary counting on pixels basically

also I saw the F=_=>() formula trick from u/KilledByAPixel's dweet that was a pottery simulator that I can't find
