Technology Alert!

This is my friend Marty at the Astronomical Society Christmas dinner on Saturday night. He forgot to bring his reading glasses with him. So suddenly I see this bright light next to me. It was coming from Marty's Samsung Galaxy III cellphone. I looked over at what he was doing and saw that he was looking at the restaurant menu with the phone. This is cool - he turned on a bright light on the back of the cellphone, and then, the camera on the back was doing video of what the light was illuminating, and it was then displayed on the front screen of the phone! It was an electronic magnifying glass! How cool is that!
