    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.

Wanted to have those 3 bars fill in all at once, but the effect is cool anyway:D

Maybe we don't have to wait 10 years. Why not just use less particles but make them larger? Plus a few bonus golfed chars for you.

Thanks for the low-res hi-fps 2019 preview! Fortunately the "record" option is able to generate the full performance hi-quality animated GIF. Here it is: https://twitter.com/rsiqueira/status/1127047…
u/KilledByAPixel

Oh wow, awesome gif! Here's my gif making tip of the day... Change the delay between frames 16 ms, so it will animate at super smooth 60 fps. You can add t/=2 before recording to prevent it from speeding up. Here's a 60 fps one I made for pavel https://imgur.com/gallery/oHiQizL
