I really like the real cubes, and the app is a neat approximation. As a writer and filmmaker, its an instant source of inspiration when I need it as well as a way to keep my skills up. However, the retina display is now officially an apple staple across multiple devices, and the graphic quality of the app is lacking. With the release of a new iPhone I hope to see an upgrade to retina graphics so using the app is as pleasant as using the real cubes.
