A few years ago I started working on a massively personalized children’s storybook called Dust Bunnies for the iPhone and iPad. One of my friends, Deanna Roy agreed to write and narrate it, another friend Lisa Merry designed some adorable characters for it, and I found a bunch of really good programmers and artists to actually produce the thing. We documented the development of Dust Bunnies, if you’d like to know more about how it came to be. We eventually released it onto the Apple App Store, and while it sold a few copies, like most iOS applications that live in the long tail, it didn’t pop. A lot of talented people spent a lot of time on Dust Bunnies. To honor their work and in the spirit of Aaron Swartz, I’ve decided to release the engine code under an Apache 2.0 license, and release the artwork under an international Creative Commons Attribution NonCommercial ShareAlike license. I really hope that people will mash it up, remix it and use it to create new wonderful things.
