The heart was showcased on Esplanade @ 4:30 during the event by firing 700+ gallons of LPG via hot air balloon burners, It also burned in the Temple (seen glowing white hot prior to Temple collapse).
Dan Fredinburg was a Google executive who was climbing Everest with three company employees while mapping the area for a future Google Earth-type project.
