I read an article recently that showed that there are restaurants the use projectors to show different colors to alter your mood as you eat!? That sounds crazy to think that while im eating you could change the way I will react with some colors and light.
I think in the article I read they were using laser projectors... from some company called aaxa tech
. Never heard of it before.
But that is some cool stuff.
Here is a picture of what it can do... found it on a djforum..
