    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.

Finally resorted to UTF8. This is a reasonably accurate slow motion aperture grille scanline animation... Although if run very slow you will see it's not simulating 3 electron beams. t=fps (scanline) w=width (subpixels) the later must be a multiple of 3 and 5. Use X, Y and floored F to plugin your own fractal!

bypassing the character limit I see using unicode escapements and regex u r very clever
