I know something of Jamie and Dyami, the brothers behind Dragon Stop Motion. Jamie and I were introduced by our sons on a bike ride in 2004.
Jamie has a long history of directing award-winning stop-motion animation, from music videos to Super Bowl ads. On top of his visual aesthetic skills, he has a long history of craftsmanship (builds his own camera motion systems, creates beautiful stereo-optical systems of glass, wood, and brass). I think the artistry runs in the family.
By the time he started working on "Dragon" for United Airlines, he had become fed up with the current state of stop motion support software, especially when it came to DSLR control. He took his concerns to his brother, Dyami, who began coding after hours to support Jamie's concept.
The interesting thing is that they were not in the same city. Dyami would code new features (including hardware control via poorly-documented APIs) and, if needed, debug with Jamie over the phone. I have run large teams of very good developers, but very few are so good they can do that type of work efficiently. Talking with Jamie at the time, he said little debug was required; he would conceive of a feature one day and would have code in production the next.
Dragon has since become the brothers' primary focus. When my 10-year-old expressed interest in stop motion, we purchased one of the first copies of Dragon. I expected it would take days for me to start using, and then I would have to teach my son a limited subset of the features. Nope--he picked it up on his own and had his first few seconds of animation that afternoon. (He now keeps his whole SM kit in a backpack so he can shoot at friends' houses after school.) Tools like onion-skinning and short sequence playback made a great difference in the quality of his work.
It says a lot about Jamie's vision and UI expertise that the same tool used for multi-million-dollar movies can also be effectively used by a child. Combined with the stability provided by Dyami's top-notch coding, we couldn't be happier with Dragon. I wish them the best.
