Dude makes doodad that can hijack any screen wirelessly

The man in this video says that he managed to cobble together a device that can hack into any screen and transmit whatever image or video he wanted on the screen.

After watching the video your first reaction would probably be, “I want me one of those doodads!”

Before you go scheming on how you going to hijack the many large screens around KL and put a video of yourself (your girlfriend or pet) on, please note that as cool as the concept is, it is not real.

Still, very cool idea/trick.
