The triple-decker “zipper” at Morgan Stanley’s 1585 Broadway headquarters — a fixture for more than 25 years — went dark last week.

But the signage will return in September modernized and more colorful, with digital technology replacing “old analog lightbulbs,” says Morgan Stanley rep Michele Davis.

As shown above, the zippers, as well as side screens and corner “barrels” to be animated for the first time, will use high-resolution technology in tune with today’s Times Square.
