Here's a short spot for Zazzle by the talented guys at Shilo. We're seeing a lot of GUIs featuring in mograph spots lately, mostly because digital interfaces have become such a big part of our lives.
This is a really good example of making an interface look fun. It features some smooth transitions and the overall style, as the voice over says, is "less rigid and more fluid".
What I really like is the sense of endless space they've created, the idea of having unlimited screen space. I also like the scene where the guy pushes the design onto the skateboard, that was a really nice touch (bad pun).
Check it out.
