    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.

I couldn't fit in scaling by "s", either via x.font or via x.setTransform or x.scale. This is also broken on iOS Safari because x.filter needs the trailing semicolon on that browser.

Massive props to JWinslow in the Discord for doing almost all of the golfing! The last 15 or so characters were removable because 1.57 is an OK approximation of Pi/2 and because the dimensions were scalable by four in the transform.

This works well in my Firefox and Safari. In Chrome it's smooth but so slow.

You can probably re-create BeesAndBombs's latest (https://twitter.com/beesandbombs/status/1024…) with this but it runs so poorly I didn't feel like doing the last part.

Runs perfectly fine at 60 fps in the iPhone browser, but a choppy 10-15 FPS in Chrome on my superpowered work laptop. What a time to be alive.

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.
