As AN reported back in early May, the Port Authority Bus Terminal was set to get a Bright Light makeover. Well, the Authority flicked on the switch of its GKD MediaMesh display this month, and as an enticement to advertisers A2a MEDIA, an advertising agency specializing in digital displays, created a promotional video using some of their established clients’ advertising. It’s a snazzy little number that doesn’t necessarily interest us for its ad content, but rather for the intriguing alternating opacity and transparency of the screen. (There are some pretty cool moments in the video below where the giant Xs of the Port Authority facade shows through the lights.) While the advertising applications are obvious, there’s definitely some untapped potential for public art/architecture, as we saw at play in California State University’s Madden Library.
