    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.

u/meowterspace

can you please explain your code so i can learn how to do this
u/vinca

I use this tool. https://imgur.com/GKPVSJd The formula for displaying this screen is "log (x ^ 2)> tan (xy)".

Awesome stuff, and thanks for sharing the tool! 111 bytes (but with no slow reveal): if(!t)for(Y=V=270,A=.03;V>-Y;V--)for(H=X=480;H>-X;H--)T(A*H)*T(A*V)>S(A*A*H*V)&&x.fillRect(H*2+X*2,V*2+Y*2,2,2)

Very rough gears. Don't try this at home.

u/tomxor

With an arrow function there is enough space for some tapered gears :) g=(a,b,n,r)=>{ then i-=d,i+.05)
u/tomxor

Arrow function seems to need a space after the } though !
u/somebody

c.width+=0 and replacing d with .1 directly saves two bytes. might be able to improve the tapering or something
