Workers are installing 288 new sparkling Waterford crystal triangles. They are being added to more than 2,100 other crystal triangles to create what's being described as a "Gift of Wonder" design.

The custom-designed crystals created by Waterford artisans are built to withstand high winds, precipitation and temperature fluctuations. The ball, a New Year's Eve icon, must be sturdy because it will rest 470 feet above Times Square.
