No. 059, in eight platesColourful Formula One

Picture a silkscreen workshop with only two buckets left, both of them hot. Colourful Formula One works almost entirely in crimson, cadmium yellow and the orange where they overlap, with the odd navy shadow for weight. The cars are flat shapes on ink-black tyres, and the tracks are built from ruled lines that converge on a single point, so each plate drags the eye down the straight like an interwar travel poster retuned for the grid.

Ruled Straight and Banded Horizon are close to pure geometry: a fan of stripes and two or three cars riding them toward the skyline. Tiled Grid swaps the stripes for a floor of squares receding between blank crimson walls, more stage set than circuit, with a yellow car dead centre. Pit Building and Colonnade Bend bring in architecture, a long grandstand in one and a row of arches in the other, while Three Abreast lines up a trio of racers below tower blocks. Two plates break ranks with a modern car. Distressed Print looks like a poster scraped half off a wall, and Sun Over the Stands throws navy spray under a burning orange sun.

There is very little dark in this room, and that is the point. Your clock will sit on a sheet of yellow or crimson, so it reads best with a white or deep red Lock Screen font. Vanishing points mostly fall in the upper third, which means the time lands near the horizon and the cars arrive underneath it. On the Home Screen the stripes make a lively floor for icons; Tiled Grid and Pit Building are the calmer choices, and a dark tinted icon style keeps every label clear.

Made for people who want a phone that looks like a race poster rather than a photo of a race: graphic designers, print collectors and fans of the louder decades of the sport. Ruled Straight and Pit Building are free, in full resolution; the other six are premium.
