Aquarium.FM — Ambient internet radio with aquatic nostalgia. A digital aquarium for the lock screen, paired with curated playlists. Tropical fish drift on their own, the music plays in the background, and the water shifts with the time of day. Ambient sound for deep work, not a screen asking for your attention.
