For me, when I am done with all of my other projects (my wife would KILL me if I started yet another without finishing the ones I currently have!!!), I plan on building this one and using two dummy video camera lenses, and one active one which will be hooked up to a 1" color LCD display. I already have all the electronic hardware, and the coolest part will be that it will be able to zoom WAY in... I will just have to remember to zoom back out before attempting to walk! The other downside is that I will have zero depth perception this way, but I am sure I can live with that!
