``` 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. ```

That's a very juicy #twister!

I teach 9-year-olds programming and used a tidied up version of this to show them how to figure out how something works. They loved it! Thanks! I've added a bit of gap between the strands to make it easier to understand, and I think it looks good. Like Math.max(180*S(a-1.2),0).

wow, i would have never thought that my recreational programming would be used for educational purposes. glad i was able to help those kids out on their journeys!

Just saw this, nice code man! Save 11 b like this: `for(c.width=i=300;i--;)for(j=8;j--;x.fillStyle=`#f`+j*15)x.fillRect(i,99-S(a=t-i/80*C(t+i/99)+j*.9)*40,1,Math.max(40*S(a-1.1),0))`

c.innerHTML=`<svg><filter id=f><feTurbulence baseFrequency=\${1/t} result=""/><feDisplacementMap in=SourceGraphic scale=\${t}>`;x.font='9in x';x.fillText(c.style="filter:url(#f)",0,1e3);

Judging by the sound of my fan, I'm guessing filters use SIMD
• u/yonatan
or maybe just if they can't find a working GPU

firefox seems to handle this one better than chrome

• Another SVG filter test
• u/yonatan
97 chars: `c.innerHTML=`<svg><filter id=f><feTurbulence baseFrequency=\${t%1} id=p>`;c.style="filter:url(#f)"`
• u/yonatan
actually less, i don't know why there's an `id=p` in there
