Looks like the skeuomorphic crowd has left the Apple building.

What exactly is skeuomorphic design? It's a visual approach that incorporates a real-world (some would say, "old") look and feel into the digital world, such as the lacquered wood and green felt of a real casino table in the Game Center app, wooden bookshelves in the iBooks app, and even flipping pages in digital books.

Apple fans are largely divided on the topic of skeuomorphic design. Some like the idea of bridging the old real world and the new digital one. Others consider real-world references to be too traditional on an iPad, which they consider a new kind of canvass for creative digital design.

But these two ways of thinking are limited because they focus solely on certain demographics, says Silicon Valley graphic designer Steve Yamaguma of . Young people, for instance, don't need outdated metaphors to help them embrace apps. Older people, though, might appreciate visual cues.

"The click of a camera, do we really need that? For most people, I think so," Yamaguma says. "It gives the sense of a real camera, the sensation of capturing an image, and also signals that the shot was taken."
