    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.

u/kan_9

So you mean the egg came first?
u/katkip

hehe
u/pavel

Isn't it obvious that the egg came first? Chickens evolved. The first chicken had non-chicken parents. This chicken hatched from a chicken egg... because it was its egg.
u/tomxor

lol, settled by semantics... so where does the chicken begin and it's progenitor end? and is that conveniently by definition when hard shelled eggs appeared.
u/pavel

What do you intend to mean by dismissing what I said as semantics? It would be true that the chicken came first if chickens were the first of their lineage to hatch from eggs but being birds i doubt that is the case.
u/pavel

Err, if they were first to _lay_ eggs, without hatching from one.
u/pavel

Point is, the egg is finalized as far as I know. Whichever example was the first chicken, by whatever definition, even if two people cant agree on a definition, that first chicken hatched from its egg and so a chicken egg came first.
u/tomxor

🤣 don't worry man, it's literally the chicken and egg problem
u/KilledByAPixel

Evolution is very gradual, new species (chicken) don't pop into existence. This can't happen because it would need to mate to procreate. Therefore there is no such thing as "first chicken", so the question itself makes no sense.
u/pavel

'Chicken' is an arbitrary human label, these can pop in. Why can't the second chicken come from non-chicken parents too? Also, we dont need a 'first chicken.' There was a time when we had no chickens, all chickens come from chicken eggs, therefore chicken eggs came first.

probably better use arc.. didnt check fullscreen before posting....

about 60 px blur was ok for fullscreen here

nice technique!

you can just do c.filter right?

I was inspired by https://twitter.com/beesandbombs/status/1221… I wanted to see if I could draw it with one stroke. Then I just started playing around. +C(r)/2 does most of the work here, if you delete it you can see the reference shape.

%24 is only there to avoid a bug in Safari from angle being too big on arc. /3.8197 is short for *Math.PI/12

One of those things that's difficult to get into 140 chars but doesn't look so impressive hah.

Note that this is done with one stroke. The drawing starts and ends from the point that touches the circle, which changes throughout the animation.
