Sure. Apple is very up-front about not wanting just a webpage in the form of an app. Since the original homepage was just that, the app required use of features that could only come from the mobile device, which include in this app, camera and tilt/motion sensors, as a core part of the experience. The app, like many, has to use Apple's in-app purchases (IAP) to allow pixels to be sold. You can buy pixels on the website or the app, but the app can't link to any path that allows a website-based purchase that skips Apple's 30% commission. And of course, even though the content is moderated before it makes it on, I had to provide methods to flag and block individual pixels, in the event someone sneaks in an offensive image. So that's in there too. Even all the above was still coming up short of their "this doesn't do enough" feeling, so an entire suite of built-in games is included, and it will expand as the pixel lineup expands. There are two so far. They're simple, but they use the graphics as a tileset.
