    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.

remix of d/21413 but coincidentally looks like d/21490 **

u/smtsjhr

(SOURCE 158/140): c.style.filter=invert()blur(5px);for(c.width|=i=1e3;i--;){w=-5*C(t/2)+5,k=w*w*C(i)+250,x.lineTo(960+(v=40*w*S(i+t))+k*S(j=i/1),540+v/2+k*C(j+w))};x.stroke()
u/smtsjhr

how to golf without giving up blur effect??
u/smtsjhr

** @ u/danny@hille.dk please see my reply in d/21490 bless!
u/danny@hille.dk

As far as i know you cannot use the "clearRect motion blur trick" on lines, because lines uses strokeStyle, you can however do somthin like this: x.fillStyle='#0001' for(x.fillRect(0,0,i=2e3,i);i--;x.clearRect(960+(v=40*w*S(i+t))+k*S(i),540+v/2+k*C(i+w),9,9))w=-5*C(t/2)+5,k=w*w*C(i)+99
u/smtsjhr

thanks again u/danny@hille.dk thats great!

webbed polygons spin themselves

looking nice
u/rodrigo.siqueira

I once made one similar, a "Polygon showcase" from 1 to 8 vertices: https://www.dwitter.net/d/10692

@ u/rodrigo.siqueira very nice and concise! i think maybe there's room there for one more loop to iterate through the "web" like
