If the video is to be believed, BITcrash44 apparently created a transmitter capable of taking over any screen within a certain vicinity, allowing him to replace some of Times Square's ads with his own video. After recording a brief clip on his iPhone 4, he proceeds to demonstrate the technology in front of various screens, before attaching the transmitter to a red balloon and "hacking" a display positioned high above him.
"[I]t doesn't matter what shape or size the hacked screen is because the hack video will simply keep its correct dimensions and the rest of the hacked space will stay black," he explains in the video's description.
We're still not convinced that this is actually real, but BITcrash44 says he'll be posting a new video later this week, to explain how he did it.
