The House Beneath the Sea — Cinematic Underwater Animation Made in Blender

A quiet day and night at ATOL — a one-atmosphere underwater house anchored beside a tropical reef, 20 metres below the surface. Sunbeams on the sand, a sea turtle gliding past, a warm living room glowing behind the acrylic dome, and manta rays feeding in the lights after dark. This four-minute film has no dialogue and no plot twist. It is simply a place you can visit: built like an engineer would build it — pressure hulls, ballast, trim tanks, an umbilical to the surface — and filmed like a nature documentary, from the first glimpse through the reef to the lights fading back into the dark water.
