Skeuomorph

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

Digital Skeuomorphs
Many computer programs have a skeuomorphic graphical user interface
that emulates objects in the physical world.

Why Skeuomorphic?
Skeuomorphic design makes it easier for those familiar with the
original device to use the digital emulation, and that it is visually
appealing.
