As I mentioned elsewhere: > Using fake depth and shadows on a design element to give it a 3D look like a real-world button is a form of skeuomorphism, because it relies on an understanding of real-world buttons that can be pushed. Note that these effects are always on objects that have interactive behavior with real-life analogies. Windows for example can be "picked up" and "moved". It casts shadows to mimic the idea of one window being in front of another. The mock-up tabs in the Win95 interface can be clicked on and also mimic real-life tabbed file folders. Yet at the same time, a table does not feature any drop shadow or fake depth effects. A table cell doesn't have a real-life analogy of an object that can be picked up and moved around. It does feature a visible grid to help eye saccades. Look up the history of the desktop metaphor. It's based on actual physical desktops. You know, the ones in administration with paper folders which contain files. For most modern people it is skeuomorphism hiding in plain sight.
