FLATIRON — A mirrored dome rose in a Flatiron Plaza this week, allowing passersby to walk through and see light, color and reflections change around them.

The installation, called "Nova," made up of multi-angled mirrors and several entrances, will officially be unveiled in the Flatiron pedestrian plaza at 23rd Street on Wednesday at 6 p.m., according to the Flatiron Partnership/23rd Street BID.

The work, conceived and built by design firm SOFTlab, is the winning project of an annual selection process organized by the BID.

“Although our design reads as an iconic and festive figure from above, the experience at the pedestrian level is very different,” said Michael Szivos, founder of SOFTlab. “The exterior gives way to a crystal-like, mirror-surfaced interior that looks different from all sides.”

The installation will remain in the plaza at 23rd Street, Broadway and Fifth Avenue through the holidays as part of the Partnership’s “23 Days of Flatiron Cheer.”
