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.
Nice work! Have a look at this if you want a circle. Change M to change the render speed --> for(i=2e3;i--;x.fillRect(i,t*M,1,M))M=600,A=i-960,B=t*M-540,x.fillStyle=hsl(${S((A*A+B*B)/9999)*99},69%,69%)
