If you’re in New York City, head to Times Square to show your love by making this 10-foot tall LED heart sculpture glow a brilliant pink. Designed by the Bjarke Ingels Group, the heart hovers within a cube made of 400 glass rods, and it pulses brighter and stronger as more visitors touch the activation pad. More people bring more love and more light, making the sculpture directly relate to the crowds surrounding it, so grab your sweetie, your friends, or even a few strangers, and help light up Times Square. But hurry, as tomorrow is the last day for the interactive installation! Hit the jump to see more photos.
