No. 003, in eleven platesArt Nouveau

Nothing in this room is shaded with a brush. Each plate is built from fine parallel strokes, like a banknote engraving that has come loose and started to curl, and the whiplash curves are what earn the Art Nouveau name. The inks barely change from one work to the next: soot black, a mossy olive, a cold petrol teal and a gold that runs from pale straw to full yolk. That narrow palette is what lets eleven quite strange pictures hang together.

The scenes lean surreal. A man in a long coat stands with his hands behind his back while a whirlwind spins open above him. Two men in bowler hats sit at a brass contraption, their heads sprouting into golden trees. A pair of electricity pylons is drawn as if knitted from fingerprints. Elsewhere a river pours down a cliff in white threads beneath a gnarled bough, cable cars climb past falling leaves, and an older couple pause by a shop window while a tree of gold billows out of it.

Most plates keep their darkest ink near the top, so the clock sits on near-black with plenty of contrast. The busier ones, such as the wall of swirling strokes dotted with tiny workers, carry detail right to the edges; pick those for the Home Screen, where icons break up the pattern, and save the whirlwind or the pylons for the Lock Screen. Because the ground is so dark, white labels read cleanly and dark mode suits the whole set.

It suits people who like a phone that looks like a print shop drawer: fans of engraving, of Jugendstil posters and of dreamlike pictures that reward a second look. Three plates are free in full resolution, and the remaining eight are premium.
