We had some videos of this on here earlier but now here's a video taken by the company that organized the Laser Show yesterday and some more info's about it.
Lupe Fiasco and Redlaser use LASERS to announce the upcoming March release of the new album: LASERS. Fitting.
Lightwave International used multiple Prism Series Lasers to beam the message on buildings surrounding Union Square. Subsequently, a mob amassed to scan the pre-release QR code. Traffic was stopped and police arrived to restore the flow of traffic: a marketing success.
