I find it amusing that the topic is good-looking graphics and the game in the screenshot looks butt-ugly, even for a lo-fi game. "Extending TK to direction of breath-taking animations" is not a trivial task. Well-designed animation subsystem that combines flexibility, ease of use and performance is actually rare beast. Even iPhone/Mac OS X CoreAnimation API is not that trivial to use for quick flexible prototyping. "Brick" engine that the author mentions seem to provide a separate domain-specific language (motion control programs) for controlling animations. Although this can be good idea, it really makes harder to combine animations with each other and other time-related tasks (playing sounds etc).
