    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.

Nice work!, I actually did try a solution with fillRect - but it totally kills my laptop, runs kinda ok on my phone though (I get around 11fps with this dweet on my laptop, 28 on my phone)
u/danny@hille.dk

btw nice trick with ++e, i haven't seen that before, I'll put it on my toolbelt right away :-)
u/KilledByAPixel

Yep, had to make some sacrifices for speed. You can do w=127 and get a pretty good fps!
u/danny@hille.dk

this is my aptempt: reduced the resolution to get at bit more performance: c.width=w=127;for(m=w*w;m--;x.fillRect(m%w,m/w,1,(Y*(o=(3-(4-5*e+S(t))**.5)/(e+1))*w+t*w&w^X*o*w&w)/w))e=(X=1-4*m/w/w)*X+(Y=-2+4*(m%w)/w)*Y
u/danny@hille.dk

with the ++e trick its only 137 bytes :-)
u/danny@hille.dk

Sorry i hadnt seen you wrote back, yep i did 127, (any pow(2)-1 will work for the xor pattern)
