Fractals, Chaos, SelfSimilarity
The following is a collection of fractal, chaos and attractors by the author.
It includes most known formulations, including but not limited to LSystems,
IFS (Iterated Function Systems), attractors and both 2D and 3D geometric fractals.
Also included are a number of numerical solutions for computing dimensionality and
other metrics.
Random space filling of the plane
Space filling of a plane (and a line or 3D) with an arbitrary shape.
Initial concept and inspiration by John Shier.
DLA (Diffusion Limited Aggregation)
Diffusion Limited Aggregation in 2D and 3D. Including constrained by a surface and
a software implementation.
The geometric beauty of leaves.

Here's a party trick for over Christmas. Get 4 large shiny Christmas balls,
some coloured wrapping paper, some lights from the Christmas tree,
and you have you own fractal laboratory to amuse yourself with over
the festive season.
Fractal Dimension and Self Similarity

Lacunarity, Multifractal spectrum, Recurrence plots, Self Similarity.
Examples of self similarity in fractals with examples from
mathematics and photos of the physical world.
I wonder whether fractal images are not touching the very structure of our
brains. Is there a clue in the infinitely regressing character of such images
that illuminates our perception of art? Could it be that a fractal image is
of such extraordinary richness, that it is bound to resonate with our neuronal
circuits and stimulate the pleasure I infer we all feel?
P. W. Atkins

"And are you not", said Fook leaning anxiously forward, "a greater analyst
than the Googleplex Star Thinker in the Seventh Galaxy of Light and Ingenuity
which can calculate the trajectory of every single dust particle
throughout a fiveweek Dangrabad Beta sand blizzard?"
"A fiveweek sand blizzard?" said Deep Thought haughtily. "You ask this of me
who have contemplated the very vectors of the atoms in the Big Bang itself?
Molest me not with this pocket calculator stuff."

I am so in favour of the actual infinite that instead of admitting that
Nature abhors it, as is commonly said, I hold that Nature makes
frequent use of it everywhere, in order to show more effectively
the perfections of its Author. Georg Cantor

The real world was full of larger structures, smaller structures,
simpler and more complex structures than the tiny portion comprising
sentient creatures and their societies, and it required a profound
myopia of scale and similarity to believe that everything beyond this
shallow layer could be ignored.

"That's here. That's home. That's us. On it everyone you love,
everyone you know, everyone you ever heard of, every human being
who ever was, lived out their lives. The aggregate of our joy and
suffering, thousands of confident religions, ideologies and economic
doctrines, every hunter and forager, every hero and coward,
every creator and destroyer of civilization, every king and peasant,
every young couple in love, every mother and father, hopeful child,
inventor and explorer, every teacher of morals, every corrupt
politician, every superstar, every supreme leader, every saint and
sinner in the history of our species lived there  on a mote of
dust suspended in a sunbeam." Carl Sagan
