Bring a Halloween night sky to your wrist. Bat Swarm is a watch face built around a procedurally drawn dusk scene: a swarm of black bats of varied sizes scattering across a blood-orange-to-purple gradient, beneath a large moon and a bare tree-branch silhouette. In front of it all, a big outlined time display stays easy to read, with the date and a stats row for heart rate, steps, and battery with charge level. The whole scene is drawn with polygons, not a bitmap. It uses almost no memory, adapts to any screen resolution, and the bats' wings flutter while the watch is awake. Looks rich on AMOLED displays and quantizes correctly on 64-color MIP displays. Always-on support on AMOLED devices: a burn-in safe low-power screen with dim time and date and a small moon-and-bat glyph, jittered every minute. Large, readable typography with dark halos so it stays legible over the scene. Fully offline. No settings needed. No permissions beyond standard sensors. The face itself has no user-visible text besides numbers, so it works for any locale. Supported devices: fenix 7 / 7 Pro, epix 2, venu 2 / 2 plus / 3 / 3s, Forerunner 955 / 965.
