Video Display that Floats in the Air
Ever wonder of watching a movie on a video display that floats in the air? Well, I guess you remember the Star Wars movie wherein Princess Leah sent a message to Luke Skywalker in a video format that floats in the air. During the 80's or 90's, everybody think it's impossible to create this technology since you cannot control the light and the colors emmited from a machine to the air to produce streaming pictures. I remember when I was in College, we were studying about TV broadcasting on how light was emmitted from a Cathode Ray Tube to the screen inorder to produce streaming pictures or what we call as Video. It's all about the "Aquadag" which captures or pulls the electrons emitted from the "electron gun" and scatter it before it hits the screen and then produces a picture. Then "interlace scanning" will make the picture move and produce a video. Today, some scientists in the US had invented a cool gadget which displays a video that floats in the air! you think it's impossible? check this out:
Note: If you want to buy this cool stuff.. make sure you have $20,000 hehehe :P
