"This odyssey all started when I invited Hugh to be a part of my parlor game potluck league that I was starting and that ultimately went nowhere. Hugh emailed me back thinking I had I spammed him. We kind of got caught up since we had first worked together on an art science exhibit for the Franklin institute in 2005. I had seen an AMAZING book called Marion Batallie, published by Roaring Brook Press. It is a pop up book where every letter has a different pop-up mechanism.

Later the same week I had a idea in while I was showering for a. Beautiful A-Z book of Hugh's x-ray photography called X is for X-Ray. I figured he had A large enough archive of images that he could just whip the thing together.

So I emailed my idea to Hugh and he was excited to give it a try and asked me to help. We started working on a print book. Eventually Hugh would create about thirteen new images for our print book. My wife Maren was writing the text. We showed the book to several publishers and the feedback was very inconsistent, some didn't like the rhymes while others didn't like the images.

After several rounds of conflicting feedback I sent the book to my friend and great writer Paul Rosenthal. Paul not only had great feedback but provided some wonderful example rhymes. Hugh, Maren and myself decide that Paul was the guy to write the text if he was interested. Luckily he was interested and did a great job of creating a wonderful series of rhymes that go perfectly with Hugh's images.

After about a year of chasing publishers the iPad came out. I realized that this book really needed to an ebook. I had seen samples of The Elements by Theo Grey and I thought our book needed similar production values. So in my initial search for an E publisher I looked up The Elements and discovered that Theo and his good friend Max had started a new company called TouchPress. I sent them an email about our book. Literally about 45 minutes later I received an email back from them expressing interest in our book. Two weeks after that we had a verbal agreement to do an ebook together. A year and a half later X is for X-ray hit the iTunes store." Mike Levad Co-author
