One of my pupils, Scott, told me a story the other day.
Scott's Dad called him excitedly, and told him to go out into the back garden. When he was out of the house, his dad shouted for him to wave his hands.
So Scott did as he was asked. Then his Dad came out.
"No. I cant see you" he said, disconsolately.
Turns out he'd just discovered Google Earth for the first time, and had zoomed in on his house. He'd fully expected the image to be in some way live.
Overall, I think I'm glad it isn't.
