The Powerhouse Museum is a museum that focuses on technology in Sydney. We had a good time there and I would recommend it as a place to pass a few hours.
I was not in 'photographer mode' during this visit - but I did stop to take this low angle, long exposure of these planes. If you look at the left side of the picture, you can see some 'ghosts' - i.e. people walking through the field of view during the shot. I always like that kind of thing.
You can can find more shots from around the world at Our World Tuesday.
