    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.

Fixed "N is not defined" error by using T *which is predefined).. onmousemove=e=>T=e.pageY/9;for(c.width=i=2e3;i--;)x.fillRect(1e3+S(p=i+t)/(Z=4+C(p)*(h=1+S(i/99-t*4)/T))*1e3*h,540+1/Z*(i-999)*3.3,s=40/Z,s)

just replace 𝘼𝙋𝙀𝙍𝙏𝙐𝙍𝙀 with Aperture. Which also is a bit heavy on the byte count.

thx to @Jenky for mouse golfing ideas. 须 = whiskers, mouse tells its position by c.width/c.offsetWidth or c.height/c.offsetHeight
