Wow, David, this is amazing! I just watched the first quarter hour or so (I'm in the office, I had to force myself to stop after that *g*), and it's really awesome — as TTStu says, just like watching a movie! 🙂
I'd be super interested in information about the effect of being featured by Apple — be sure to come back and tell us about it!
BTW, how did you set up the scenes, if I may ask? Did you create a special software to set up the elements, which is then loaded by the app?
In any case, I wish you good luck on the App Store!! Definitely one of the greatest Sparrow apps I've seen in the past! 😎
