“A week before the torch arrived in the Olympic city, Vancouver’s skies were already illuminated, ready to greet the world with a warm welcome. Light artist Rafael Lozano-Hemmer and his team had installed 10 searchlights on both sides of English Bay for an interactive work he calls “Vectorial Elevation.”

The lights in this large-scale installation are visible within a 10-mile radius — each light shines at 10,000 watts — and anyone with access to the Internet can try his or her hand at changing the projected patterns.” Found on Art Beat via @PBS.
