    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.

You missed it

in that case, i loved it! 5 stars
u/SpecialAgent

I thought the characters were underdeveloped but the effects hit the spot!
u/joeytwiddle

I was really confused why some of the lines appear softer than others. Finally realised it's because the canvas is scaled down

Green, but the blips are harder to see

u/sfz

Increasing alpha helps see them, but makes the line sweep less cool
u/magna

They are ninjas. Harder to see.
