Faberge eggs — yes, those ornate, old-fashioned bejeweled eggs often displayed in museums — are getting a 21st century makeover. Famous artists and designers (Tommy Hilfiger, Jeff Koons, “Where’s Waldo” creator Martin Handford) are creating 2 1/2-feet tall eggs that the public can hunt for in New York City — with their smartphones.

Easter Bunny Gets Pulled Over

Over 200 of the egg sculptures will be hidden around the city in the weeks leading up to Easter, April 1-17. A free app lets you check in when you find an egg. After 10 people check in, the location pops up on an interactive map. Whoever finds the most eggs each weeks gets a Faberge necklace.

After the hunt, the eggs will be on display at Rockefeller Center, before being auctioned off for charity by Sotheby’s. In 2012, a million people participated in the debut event in London, making it what most believe was the biggest egg hunt ever. Last year, host cities included Glasgow, Scotland; Liverpool and Manchester, England; and Dublin.

“With original Faberge eggs going for up to 18.5 million dollars these days, the Sotheby’s auction could provide a chance to get an egg for a slightly more accessible price,” writes HauteLiving.com.
