In 2004, during a lunch break from a totally unrelated meeting upstairs, I had 40 minutes to take pictures in the Powerhouse Museum, Sydney. This is a wonderful place; you need a lot more time than 40 minutes. That was a quite unrepresentative sample of what was on display there, and I resolved to go back.
Now, in 2007, I've added more pictures taken in a more leisurely visit, mainly of different displays. Still not very representative. Note the long exposure times used on both visits; I avoid using flash, especially in a place like this, but this means pushing the sensitivity setting up and hoping the anti-shake will cope.
2014: Another visit, another camera, new exhibits. 2016 And again, with a good look at the Strasburg clock model.
