I don't often talk about it, but I own a little house in Sydney bay. It's not much, but I'm proud of it. The problem is that it is only virtual and made out of Lego. This wonderful site allows you to design houses, or anything else, with virtual Lego on a virtual plot in Australia or New Zealand. It's like a simplified version of SketchUp, great for younger children.

"Lego seems to never wane in popularity and my class love it. This site allows you to convert a photo into a blockish Lego image - great for profile pictures and class displays."
