A matte-black espresso machine on a concrete counter with steam and morning light

Steam rises and drifts left, the light slowly warms, camera pushes in very
slightly. Everything else stays still.

A hyperrealistic macro photo of tiny, miniature surfers riding ocean waves
inside a rustic stone bathroom sink. A vintage brass faucet is running,
creating the perpetual surf. Surreal, whimsical, bright natural lighting.

A surreal, cinematic macro video. Tiny surfers ride perpetual, rolling waves
inside a stone bathroom sink. A running vintage brass faucet generates the
endless surf. The camera slowly pans across the whimsical, sunlit scene as the
miniature figures expertly carve the turquoise water.

Smooth continuous transition between the two framings, no cuts, natural
lighting change

The character turns from the window toward the camera and smiles. Room tone
and distant traffic. No cuts.

The character performs the motion from the reference video, keeping their own
clothing and appearance
