The sample application to accompany my conference talk "Enter The Matrix" on matrix transformations. Abstract: Matrix transformations can make your user interfaces come to life: translate, scale, and rotate. Each on its own is relatively simple and straightforward. Yet many developers are daunted when 2 or more operations need to be combined. What if you need to rotate or zoom about an off-center (or even off-screen) point? How do you combine multiple transformations into a single animation? Learn everything you need to know to get started with complex matrix transformations in CoreGraphics and CoreAnimation.
