    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.

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)

I have no idea what I am doing

u/Xen

you can edit dweets directly and it gives you an option to post as remix to give credit to the original author,, have a play about with different dweets, mess with variables or completely change draw method, feel free to join us all in the discord chat https://discord.gg/emHe6cP
