3 LEDs is not enough. You need something to make the beam scan the  
wall rectangle you want to display on. This usually requires some  
mechanical parts.

Well, there is a different approach (I think has been shown by  
Siemens mobile during CeBIT: 
business/410807/ ): a micro-beamer.
Everything miniaturized so that it fits into a phone. Unfortunately  
its illumination intensity is small or it gets very hot...
