Haha, thanks Daniel 🙂
I very nearly included Stille Nacht as an alternative to Silent Night, beautiful song, much better in the German, but alas time and market share rule!
This app I believe shows off the beauty of using Sparrow hybrid apps, yes there ARE other christmas carol apps out there, I downloaded them, and they don't have the visual finesse, rather bog standard UIKit, simple pages blah blah, but using Sparrow you get things like Particle Emitters to add a whole other layer! And tweening the bouncing ball is a no brainer.
