Interface Design Concepts

A nice roundup of some interface design concepts over at the Fast Company design blog: I'm particularly taken with both the DJ turntable concept because it doesn't shy away from expecting users to develop a knowledge of how the system works, and isn't a slavish replication of both the appearance and interactions of a real-world system. The Mozilla Seabird phone concept is quite compelling too, since it breaks the screen entirely, extending it into the adjacent space for users.
