    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.

damn damn damn... wonder what is the space between the two = after for(c.width| if I replace it by a normal space it kills the dweet :|
u/danny@hille.dk

+(+!+[]+[+[]]) is a slightly less verbose way to write 10, withou using any digits
u/danny@hille.dk

for(c.width|=ﾠ=ㅤ=+(+!+[]+[+[]]) ,x.scale(ﾠ,ﾠ);--ㅤ; ) x.fillRect(S(t)*(ﾠ+ﾠ+ﾠ)+ﾠ*ㅤ+ﾠ+ﾠ+ﾠ+ﾠ,ﾠ+ﾠ+ﾠ+ﾠ,ﾠ/(ﾠ/ﾠ+ﾠ/ﾠ),ﾠ+ﾠ)
u/danny@hille.dk

or less obfuscated : for(c.width|=a=i=+(+!+[]+[+[]]),x.scale(a,a);--i; ) x.fillRect(S(t)*(a+a+a)+a*i+a+a+a+a,a+a+a+a,a/(a/a+a/a),a+a)

So cool! haven't seen anything like this before.
u/KilledByAPixel

Thanks! It is an original idea but may have been done before. Need to experiment with it more.
u/tomxor

After pulling it apart this is a lot like the doom fire et al - as an automata it is a non-totalistic anisotropic neighborhood. But having it interact with the static geometry as part of the state is a neat idea. I used a similar technique here: d/18720 but no interesting geometry.
u/tomxor

Now you got me back into automata again :P wondering what other fun anisotropic neighborhoods there might be.

this is incredible

One trick here is f();g();h(-1,-1) is the same as h(~f(),~g()) when f and g return a falsy value, undefined in this case.
u/pavel

Notice how none of the distance variables are based on time, only angles are, yet the distances are changing and nothing is rotating...

Try making the moving a little faster :)

After I wrote this I looked for other dweets using a similar technique and this is the earliest one I've found, and it includes an explanation d/10212
u/KilledByAPixel

Amazing work! I have not seen the ~ before, will be using it a lot now. I tried to explain the 60*t trick in one of my blog posts, https://frankforce.com/?p=7160
u/pavel

That is an amazingly detailed explanation with great visual aids.
u/pavel

To clarify your explanation, any integer time works. 60*t is naturally an integer (ish). frame is one char longer without numerical errors. In general, (n*t|0) works for any n.
