Hot: how to hack video screens on times square!

By a few days I came across a video on a demonstration, the transmitter is connected to a remote chip iPhone (which can work on any smart phone), just amazed me, the guy turned on the video
 
and stood with the chip in front of a screen and dry the transmission and broadcasting its own signal (what's on the phone) just brilliant. There simply would just wish it was illegal. But as a hobby, it's quite nice just wish it BETA version, meaning Shlsabevim you can not cover electrical shock. Hopefully these guys will work and market the product. So we all be one. Think joy that is kind of fun you send a picture from mobile screen at home without a connection, he has no problem transmitting sound.
