New York City's best holiday windows

Millions of viewers across the country will tune in Wednesday night to watch the iconic Christmas tree lighting at Rockefeller Center.

Although the spectacle is sure to add even more sparkle to the New York City skyline, that's not the only New York spot showing its love for over-the-top holiday décor.

Over the past few weeks, retailers across the island of Manhattan have lifted the curtains on their extravagant holiday window displays, which bring the holidays to life—and draw shoppers to the store—through high-tech exhibits.

Among them, a journey through the universe at Macy's, a modern take on classic fairy tales at Saks and interactive gaming at Bloomingdale's.

"It's cool to think that this sort of structural thing that was the store is not as hard and fast and structured as you would think," said Jeremy Bergstein, founder of The Science Project, which powered Bloomingdale's windows. "Bricks can't contain it."
