The TED Projector

What an awesome piece of technology.  I already want to go online and order one, but I know I have to wait.  The "Sixth Sense" is almost too good to be true.  But you have to think about the flip sides to everything.  What if you walk up to someone and it gives you incorrect information?  Or what happens when you start relying on this thing for everything in your daily schedule, and the batteries die?  Too much? I don't think so, because it's the same as if your batteries die on the iPhone.  However, this is a wonderful piece that I think can really help students learn about the environment and economy with 'outside the classroom' instruction.
