Lights, Camera, Action.

Alighting for an evening.

Central, Hong Kong — Birds fly across the International Commerce Building — once the fourth-tallest building in the world — as laser beams and search lights streak across the sky.

Their feathers are built of blinking offices.

The Symphony of Lights takes place across the Hong Kong Harbour every night for 10 minutes at 8 p.m. and draws quite a crowd. You can even listen to accompanying music performed by the Hong Kong Philharmonic Orchestra through an app — if you can hear it over the revellers on the party boat.

Or the amplified singers down at the pier.

Buildings on both side flash like strobes, celebrating the city. Choreographed images light up otherwise boring office windows. Neon signs blink in unison.

There are worse ways to spend an evening than with a box of takeaway dumplings — pork, and kimchi — and a beer, sitting on the pier.

Nearby, a model preens to her own portable lights as five photographers take their best shots. A bride and groom stride down the pier to capture their own memories.

The hearts cascading across the tower across the bay, it seems, are appropriate.
