    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.

c.width=640 x.stroke(new Path2D(M 180,190 l ${[[C(t)*64,Y=64*S(t)],[(80*80-Y*Y)**.5,-Y]]} 64,0))
u/donbright

that golfs it down from 127 to 98
u/donbright

ok we can go lower. 94: c.width=640 x.stroke(new Path2D(M 180,190 l ${[C(t)*64,Y=64*S(t),(80*80-Y*Y)**.5,-Y,64,0]}))
u/donbright

you have to put back tickmark right before M and right after 64,0]} .. dwitter comment seems to eat the backtick
u/f8f82804

yeah, in comments backticks are used for code blocks
u/f8f82804

I don't know if it's possible to escape it with a backslash like \ or fillStyle=\hsl(...)`
u/f8f82804

...apparently escaping does not work
u/f8f82804

also, that's an excellent path2d use! you should post a remix

Glad to see this code is blocked by the <iframe sandbox="...">

u/joeytwiddle

But what is stopping it from running here? https://www.dwitter.net/e/9056
u/joeytwiddle

Oh easy answer: The embed page also uses the same <iframe> :-)
u/joeytwiddle

For some reason I thought the embed route returned a page without an iframe. Is there any route which does that?
u/joeytwiddle

Ahh here is the non-sandboxed URL: https://dweet.dwitter.net/id/9056?autoplay=1
u/joeytwiddle

Oops the URL I had meant to share was http://www.zombo.com
