coloring book...

Hello everybody. Well, I just managed to publish my first book called “Fractal Life 247 Coloring Book”. A coloring book of all things! Lol. :^) Well, it's 99 pages of some of my algorithms that I managed to render in a way that are able to be colored by others. Mostly vector fields, escape time fractals, some triangle and circle work, ect... I actually coded up a C++ program that generates the book. So, its rather interesting. It was a pain in the you know where to get the margins, trim and full bleed factors right, but it finally passed verification. I set the price at 7.42$. I was thinking about 11.42$ but chose the previous prime from 11 at 7. Then, after I submitted it, I noticed that 7.42$ is 247 in “Fractal Life 247” in reverse! Strange. 742 is a fun number! Well, is the price okay? Too expensive? This is my first book and setting the price is harder for me than creating a new algorithm. Very strange indeed. Oh well.
Any thoughts?
Thanks everybody. :^)
