LI-FI Demonstration

Here is the actual demonstration of Harald Haas's LI-FI technology concept. The video speaks for itself but the low down is Haas streaming a video using LED bulbs. He also demonstrates what happens when you step in front of the receiver from the light emitting data source. The demo should provide a glimpse of a possible future where light gives information out to people as apposed to what we have today. The video's website gives a more descriptive summary of the video if you wish to visit it.
