LIVING BACKGROUNDS Swipe through a gallery of hand-built backgrounds that drift, glow, and breathe: - Aurora, a living color gradient - Cosmos, deep nebula with a twinkling starfield - Borealis, northern lights over a starry sky - Horizon, a cinematic sunset - Ridges, misty layered mountains - Mercury, flowing liquid metal - Artwork, an editorial sun over hills - Contemporary, minimal drifting light - Pattern, a pulsing halftone wave MADE FOR STANDBY Leave it running while charging and the screen stays awake with a calm, always-on display. A matching widget brings the binary clock to StandBy and your Lock Screen.
