Hi everybody, this is another little image produced with
CSS -- sorry, I didn't have ideas about anything
more interactive than images :-)

The code is a single for loop evaluating the following formulas:

	w(n) = a * x(n) + (2 - 2*a) * x(n)^2 / (1 + x(n)^2)
	x(n+1) = b * y(n) + w(n)
	y(n+1) = w(n+1) - x(n)

with a = -0.8, b = 0.9 and starting with x(0)=4, y(0)=0.
The formula produces a nice feather-like pattern for 2500
iterations, then converges to (0,0) abruptly.

For each iteration, a P tag with absolute positioning is written
in the document.

Have fun,

Hi everybody, here is my first JavaScript program:
a Mandelbrot set in 251 bytes!

To the brave who want to read the program and never
wrote optimized JavaScript:  I took maximum advantage
of for's three arguments, so the body of each for is just
another for:

   for (a;b;c)
     d
     for (e;f;g)...
     h
     
becomes

   for(a;b;h,c)
     for(d,e;f;g)...

and this saved me at least 15 bytes.  Also I used > tests
to avoid having to escape the < (that is, 4>r*r+i*i instead
of r*r+i*i&lt;4).  The code is a standard (though size-optimized)
Mandelbrot set algorithm, with the output concatenated into a
variable (d) a line at a time.  The colors are obtained by putting
each output inside a <b> tag with appropriate CSS styling; the
formatting is done with a <pre> tag so that a new-line (\n, two
characters shorter than <br>) suffices to end each "scanline".
Note that the output of each scanline is computed right-to-left
to save a comparison on the x (x instead of x<80).

Since the presence of 96*80=7680 tags with CSS styles can
easily bring your browser to its knees, I included an ASCII only
version which produces a single character for each position, but
is a lot less pleasing to look at.

Have fun,

     while computing ( ~45 seconds @ my
