I love the idea and would definitely recommend you develop it further. Have you seen the Climate Change Coloring Book? It did reasonably well on Kickstarter (raised $24k, although after printing and shipping that might not leave much) and I just got my copies about a week ago. I ordered 5 to give some as gifts. I'd easily order a few of yours and give one to my dad (former coder) and my kids.
Thanks for the encouragement. I have seen that book, and ordered one myself as well! I would be thrilled if my book could match that success on Kickstarter. To hear you say you'd give it as a gift is awesome, so I'll get to work =)
