Workers installed 192 glittering Waterford crystal triangles on Times Square’s New Year’s Eve ball Sunday in preparation for a pandemic-limited celebration that will lack the usual tightly packed crowds of revelers. The ball is a 12-foot geodesic sphere covered with 2,688 crystal triangles of various sizes. Some new crystals are swapped in every year. This year’s addition features a new “Gift of Happiness” design represented by a sunburst of bright cuts radiating outward. The ball blazing with 32,256 LED lights will be dropped at 11:59 pm on New Year’s Eve to ring in 2021. Performances at the event will be designed for TV audiences watching from home.
