Often times the best designs come about when the designer is forced to deal with constraints. In this case some terrific architecture and landscape design has come out of the space constraints presented by the rooftops of urban buildings.

When designers are forced to think about space differently they will come up with ideas and concepts that they would not have otherwise.

I am hoping to see some very interesting things in iPhone application design and pushing what that platform has done and can do in terms of the interface and experience.
