For four years, Times Square has hosted an annual heart sculpture to celebrate Valentine’s Day. This year’s 2012 Times Square Valentine heart sculpture is “City Pulse” by BIG Design. The 10-foot tall glowing sculpture of 10 transparent, LED lit, acrylic tubes that form a cube around a suspended red heart. The hovering heart will appear to pulsate. As more people gather around the illuminated sculpture, the heart will glow brighter as the energy from their footsteps is converted into more light.
