skeuomorph

A skeuomorph is a physical ornament or design on an object made to resemble another material or technique.

The latter has led some archaeologists to argue that the style is a skeuomorph and is derived from wicker basketry.

A skeuomorph is a derivative object that retains ornamental design cues to a structure that was necessary in the original.

After the demise of actual wood construction, manufacturers employed skeuomorph to recall wood construction - using, for example, simulated wood-grain sheet vinyl at times augmented with three-dimensional, simulated framework.

A similar alternative definition of skeuomorph is "an element of design or structure that serves little or no purpose in the artifact fashioned from the new material but was essential to the object made from the original material".

The shutter-click sound emitted by most camera phones when taking a picture is an auditory skeuomorph - it does not come from a mechanical shutter, which camera phones lack, but from a sound file in the phone's operating system.
