    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.

what is $ for?

${x} surrounded by backticks is ES6 javascript syntax - it puts the value of x in the string

${} is usually more characters than string concatenation, but if you're doing mathematics in the expression (like "(a/Z/20)-i%4*9" here) you end up needing to surround it with so many parentheses if you're doing string concatenation that template strings are handier.
