Check this out in the mean time: Leo Burnett’s design studio. You will be impressed with the design, variety of user-interface solutions and visual effects.
I fancy the idea of making non-linear interfaces and avoiding menu-ish look. The existing paradigm has turned into habits of our users already and its dearly hard to break this stereotype. The more applications we write, the more our users go down into the swamp of their stereotypes. The sites (which are also the applications of some sort), like Leo Burnett’s, is a lot of fun to the visitor not only for its fancy graphics, but also for its navigation approach. It doesn’t grate on your eyes since it looks unusual and surprising at first. Two minutes of education and you are “operating” the site, like a pro, since it’s still intuitive and easy to learn.
When you are in “free flight”, it’s hard to maintain overall style and paradigm of your user interface because you aren’t bounded in your choices and it’s up to you how your creation will look and feel.
