    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.

121 for(c.width|=p=15;p--;)0x24f7fbef924fef3fce7c9edf3cfcf9e4927b6fn&1n<<BigInt(~~t%10*15+p)&&x.fillRect(p%3*T,p/3*T,T,T=200)

Also 121 but with neater output for(c.width|=p=15;p--;)0x24f7fbef924fef3fce7c9edf3cfcf9e4927b6fn&1n<<BigInt(~~t%10*15+p)&&x.fillRect(p%3<<6,p/3<<6,64,64)
