An ancient brand gets a truly modern makeover for the Easter season at an iconic department store — and showcases the massive power of window dressing along the way.

Harrods’ flagship shop in the Knightsbridge hood of London has bedecked its jewel of a window case with a digital masterpiece to mark this herald-of-spring holiday. Celebrated luxury jeweler Fabergé has unveiled an oversized digitally decorated egg that invites passersby to gather in camera-phone-toting throngs in its presence.

Displayed across four of the store’s Brompton Rd. windows, the display features a truly remarkable projection show that unfolds on a 1.5-metre three-dimensional egg-shaped model. Using projection-mapping technology by Projection Artworks, the spectacle applies large amounts of light to relatively small areas. This unprecedented projection method — courtesy of recent advancements in small-scale projection technology — allows the visuals to be seen in all kinds of light, including daylight.

Shoppers in the store can participate in the fun via interactive touch-screen technology that allows them to customize the digital patterns that explode across the egg. These range from Fabergé’s detailed Impératrice design set with green tsavorites to its Emotion design, which is elaborately wrapped in pavéd diamonds, sapphires, emeralds and rubies.

In response to media delight over the unique display, Projection Artworks managing director Tom Burch said, “This kind of installation would never have been feasible a few years ago and the projectors would have been enormous.”

The display, undertaken in partnership with creative agency Just So, marks Fabergé’s opening of a pop-up “egg bar” on the store’s ground floor. The distinctive installation will light up Harrods windows until the close of Easter.[su_vimeo url=”https://vimeo.com/122094372″]
