Skeuomorphism
Digital things dressed as physical ones: leather stitching, brushed metal, felt, real switches. The pre-iOS 7 iPhone look.

What it is
Skeuomorphism dresses digital things as the physical objects they replaced: stitched leather calendars, green felt card tables, brushed metal panels, yellow legal pads, knobs and switches with real highlights and cast shadows. The word comes from the Greek 'skeuos' (vessel, tool) and 'morphe' (shape). Apple's pre-2013 iOS, GarageBand, and Game Center are the canonical run, killed off in one release by iOS 7.
Reach for it when the metaphor genuinely teaches: audio and music tools where people already know what a fader or a tape transport does, children's apps, nostalgia products, and anything that wants to feel handmade rather than systemized. Done well it makes an interface instantly legible with no onboarding.
Gotcha: the metaphor expires. A save icon shaped like a floppy disk teaches nobody under thirty, and mimicking a real object drags its limits along with its look (a page-turn animation that can only turn one page at a time). It's also expensive: every state of every control needs hand-rendered art, at every screen density, in every theme.

Design this interface as full skeuomorphism, in the style of pre-iOS 7 Apple apps. Give surfaces real materials: stitched leather headers, linen or felt backgrounds, brushed-metal panels with a subtle vertical noise texture, and paper with a torn edge. Every control should look physical: rounded glossy buttons with a top highlight, a 1px inner light line, a soft cast shadow below, and a pressed state that inverts the gradient and sinks the shadow inward. Add warm ambient lighting from above, real drop shadows between layers, and serif or engraved-style labels. No flat fills anywhere.
