    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.

Dweet illustrating how t diverges from time reported by getTime() as framerate gets lower. Warning: this dweet intentionally loops for longer and longer, and will probably eventually lock your browser if you have it on screen for 20 minutes.

Why is the joker the only card that gets its own emoji?

u/fujimotos

It seems to me that unicode table owns the full deck of cards: http://www.amp-what.com/unicode/search/card
u/Agnes

Interesting! Several of those straight up don't render for me. Only the "black joker" has a colourful emoji representation, the rest are transparent utf-8 ideographs.

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.

Zamboni simulator. Numbers were chosen to work with Chrome emojis. Probably breaks with any other set of emojis; sorry about that.

Just realised there may be a way cooler way to do this with shadowBlur.

What colour is your easter pig?

u/Agnes

(Sometimes you don't get an easter pig and sometimes the pig is a ghost, but I think that improves the dweet and I don't have the characters to fix either bug)
u/chokezonhorsey

haha.. i love it :))
u/BirdsTweetCodersDweet

Apparently c.width|=q=t<10;f=t?q?(f/Math.random())%9e3:f:1;x.font=512*(q?t/10:1)+'px A';x.fillStyle='#'+!q*~~f;x.fillText("🐖",660+t*q*f%5,740) fixes the ghost pig on mine :P
