skeuomorphism
Skeuomorphism is a graphic design technique primarily used in technology, where things are made to resemble their real-life counterparts. This typically corresponds with a more glossy, 3D look as opposed to a flat one.
For example, a minimalist icon of a camera app will be a flat and unshaded silhouette, while a skeuomorphic icon will have a detailed lens, rounded, glossy corners, and other details to make it look more like an actual camera.
