    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.

Click the present for your random gift. I wanted the present to move around and shake until you clicked it, but couldn't make it happen with the required function calls.

u/prplz

Golfed c.onclick=z=()=>{c.width|=0;x.font="16em A";x.fillText(String.fromCodePoint(127873+t*60|0),832,668)};t||z()
u/prplz

Ah i just realized that won't allow you to do the movement you wanted, but there are some other tricks there
u/Agnes

Thanks for the onclick tip! That kind of allows me to do the shaking.

Hi Joey. Beesandbombs is cool. I tool a look at his animations and the code that generates them at github. Very cool. Still his stuff would be require many hours to reverse engineer. Your effort to move one his animations here is nice work. Thanks for bringing him to my attention.
u/joeytwiddle

I sometimes post his tweets in the Discord channel, as inspiration for dwitterers with dweeter's block. Agnes posted a prototype and we hacked away at it. :D Let's keep sharing the fun ones!
