New Release – Adult Coloring Book: Fractals

So here’s what I’ve been up to the last couple of months…


My latest book, Adult Coloring Book: Fractals, is available now on Amazon!

I’m excited to publishing this book with Green Frog Publishing, a small Indie Publisher based in Vermont. This book is actually the second in a series of coloring books, the first of which is a great set of hand-drawn images of the Adirondacks by Dave Campbell.

This book has been a real collaborative effort, including the proofreading talents of one Mr. Brian Buckley, cover and website art by my wife, and editing by Cecilia Bizzoco. Green Frog’s been just great, providing a lot of personal attention and developmental feedback to make this a better book than anything I could have done alone.

The Adult Coloring Book: Fractals is a collection of 25 fractal images for you to color and enjoy. Along the way you’ll learn the basics about fractals, and how some of the individual images were created. Most of this is all new material exclusive to this book (we’ll talk more later in the week about the production process). There’s also an extensive glossary with even more fractal explorations and resources (any glossary that includes a definition for the “Genesis Effect” is okay in my book).

I think fractals are uniquely suited to adult coloring books in that they offer a lot of freedom for interpretation. How you color these images is entirely up to you. Just seeing some of the work my wife put together really made these fractals come alive for me.

You can check out some of the images from this book on my new website BenTrubeFractals.com or buy the book from Amazon.com. Particularly check out the “Play with Fractals” tab for some of the unique L-Systems in this book.

The Fractal Man (Axiom)

The third iteration (part) of my serial short story will be posted on Wednesday. For today as I sit here in my church listening to some live killer sax (from Molto Cappriccio) and waiting for 147 Windows 7 updates to install, I thought I’d give you a little background for this story, and to reassure some of you that most of it is fictional.

As with a lot of things here on the Blog, this short story is an experiment, a little bit of a departure from my regular genre to write a more introspective piece. My mom said this is a very “English major-y” story. I’m not sure what that means, but as a writer I like to think I can write any sort of genre, hopefully still with my own voice.

This much is true about the story you are reading, whenever I look at trees I see fractals.

It doesn’t quite rise to the level of affliction as with my character, but it is definitely a change in the way I perceive reality. Apparently spending a year and a half in deep study of the subject (and if we’re honest fairly continuous interest afterward) can cause the way you look at the world can change. I don’t know if this is permanent and it isn’t the same for every tree. We visited Jekyll Island for vacation a few weeks ago. There the trees are palm with Spanish moss growing all over them. Though I know they can be modeled with fractals, I haven’t yet studied the method deep enough, and it was somewhat calming to just see trees and not fractals.

I do sill love fractals, I wouldn’t be contemplating writing a second volume about them if I didn’t, but it is fascinating to observe how what you put in your head shapes you. If I had spent the last two years deep in revision in Dark Mater, or writing the next two Surrealities, no doubt my view point would be very different.

Another inspiration for this story is the book The Man Who Mistook His Wife For A Hat, a book containing narrative case studies of various mental afflictions. I found this book deeply fascinating, particularly the ways in which the patients perceive reality, or unreality, when certain parts of the brain are damaged.

As for why I’m writing this story there are a couple of additional reasons. I was a little geared up to write a story this weekend for the NYC Midnight contest, and though I sadly didn’t make it to the second round (though friend of the blog Jo Eberhardt did and hopefully her latest story went well), I wanted to have a place to spend that energy. And as far as process goes, this story is being written on the fly, in much the same fashion as Denied the Stars last year. I know where the story is going, and most of the component parts in the middle (I didn’t avoid going to Vegas just because I’ve never been there in real life, though this be madness and yet there is a method in it). Oh and I know trees aren’t dead in the winter, they lie dormant, but to my character they appear dead. Foreshadowing, or setting a tone ;). Each iteration is written the day before it is posted, usually in about in an hour.

So be sure to check out the first and second iterations before Wednesday. Hopefully you’ve enjoyed the story thus far, and where it is going. Feedback is definitely appreciated. I post stories like this here to learn what works and what doesn’t, so feel free to say anything. And feel free to ask any questions I haven’t covered here. You never know I might answer 😉

A Fractal For Friday

I’ve been messing around with some new color algorithms, as well as complex trigonometric functions. I have a lot of pictures I want to show you, but for now we’ll just go with one of my favorites for the week:


And yes, if there was ever any doubt, I’ll probably be writing a volume 2 of the fractal book, but I promise I’ll finish Surreality first.

Happy Friday!

Bonus Friday Post “First Fractals of the Year!”

For today’s post I thought I’d take you through some of my “creative process” for playing with L-Systems, fractals created using an algorithmic grammar.

We start with a simple shape:


This shape is my “replacement rule” for the L-System. To draw this shape I use the sequence of letters F-F+F+F-F, with F meaning “draw a line forward”, ‘-‘ meaning “turn left 120 degrees” and ‘+’ meaning “turn right 120 degrees.” If I start with a triangle, and replace each side of the triangle with this starting shape I get the following:


If I repeat this for each line of the new shape, and again on each line of the resulting shape, after a few iterations I get this:


The Sierpinski Gasket, one of the most persistent recurring fractals with untold methods for drawing it.

But what if I didn’t start with a triangle? What if I started with a square?

Then I’d get this:


That’s pretty good, but if what if inverted the square by flipping it inside out. A typical square is drawn F+F+F+F with ‘+’ being a right turn of 90 degrees. But if I change those pluses to minuses I get this:


And here’s what an inverted pentagon would look like:


Okay, that’s pretty good, but what if we skewed our initial replacement shape?


So now our initial triangle would look something like this:


Keep repeating this process and you get something really different:


Same number of lines that we used to draw our Sierpinski Gasket, but with less overlap (this is one of my favorites). Let’s try another skewed shape:


And the resulting first stage is:


Now what do we get?


That’s good but let’s invert it. Our first stage is:


And after a few iterations we get:


Now let’s start with an inverted hexagon:


And see what happens:


If we turn the hexagon right-side out:


We get this:


But L-Systems also allow for moving without drawing a line, typically represented by the ‘f’ character. Let’s take our first motif and remove a section:


If we apply this replacement rule to an inverted triangle we get this:


And after a few iterations:


Turn our triangle right-side out and we get:


Followed by:


Here’s a couple other skip motifs:


And the result:


Initial Stage:




Now let’s remove some sections from our skewed replacement rules:


First Stage:




Replacement Motif:


First Stage:




Each of the above shapes had no replacement rule for ‘f’ so these segments were kept empty. If we use the same replacement rule for ‘f’ as we do for ‘F’, we get these respectively:


And this:


Similar to our originals, but with less internal lines.

Finally, let’s look at a couple more variations. A wider initial stage can stretch our gasket:



First Stage:




And a hex-bump creates a non-overlapping curve.



First Stage:




All of these shapes were created from variations on a five-line motif. Hopefully you can see from this post how tiny variations in method can create huge changes in result.

Have a happy fractal friday!

Fractal Friday “Grayscale Friday”

I’ve been experimenting with some black and white fractalizing, using a couple of new grayscale and inverted grayscale color filters on my Mandelbrot program. Here are some of the very preliminary results:



The inverted grayscales are the ones with white Mandelbrot sets.





Happy Friday!
