Thanks for the comments. Don't worry. I didn't take offense.
It was a tough problem for me to figure out. I bounced around with The Unofficial GameSalad Textbook. I switched between so many different formats... PDF, ePub and App. The app version was popular. Apple featured it. There are strong arguments for creating an App. I had to make a decision. Even just starting this project was tough. So, I picked iBooks (ePub) because I could focus more on writing / creating content, rather than battling with different formats.
I've been working on templates for the book. Here's an example of some JavaScript... Geometry question - #2 by Photics ...the goal is to push designers to learn programming – and programmers to learn design. Lots of people say, "I can't code." They also might say, "I can't design." Hopefully, this book can help people get past that.
Over the weekend, I visited Manhattan. I took some pictures as a plan for the cover.
Also good news, there's a decent chance this book will be translated to German. If Hype supported Polish, that might be a possibility for the book too. But right now, no other languages are planned for launch though.
