In one example the LED controller detects where the subject is located and which way he or she is facing. I believe the system I am referring to was designed by Lunar Accents Design ( <a href="http://www.LunarAccents.com" rel="nofollow">http://www.LunarAccents.com</a> ). I have also seen other LED control systems in the airport which detect the movement of passengers going through the metal detectors.

Some of the above posts reflect highly evolved egos. I agree with the comment made by Phil. If you had done something like this in the past but did not take the time to create a video record of the event, your experience is irrelevant to us. The community would be better served if, instead of announcing your superiority to the world, you recreated your work and supplied us with a video record. In other words, put up or shut up!

The earlier posts on his blog are mostly in a similar vein, combining a couple of simple hacks to make a neat device. the laser gesture-control coupled to a serial port relay for controlling electrical items is a neat hack that I'd like to try.

I took issue with mixing country music with hacker video.
Otherwise, nice programming.

I love this site, it’s the smaller hacks that help me to understand what will be possible when I’ve finished learning my uC programming and give me an idea of how much can be accomplished within reason.

Sure, it's not new, but it's a new (it might have been done before, but I haven't seen it) mix of old hacks. I like it. :D Thumbs up for the work and I'd like to see what people do with this in the future. This is an interesting hack.
