Crowd-watching is one of those perennial favorite activities that never seems to get old no matter how often you do it. For the 2011 Vancouver Celebration of Light, a popular annual fireworks show, Dave Delnea Images documented the huge crowd gathering, reveling and then dispersing.

The video produced by the firm shows a vibrant crowd flocking to the beach to watch the light show. From the high vantage point, each of the individuals melds into a part of the larger throng.

The fabric of the crowd weaves itself into a colorful tapestry that writhes and undulates, never sitting still.

This short video is a perfect examination of the energy of city life; the urban landscape is enhanced and defined by the people who inhabit it.
