Sketchup is a really easy to use 3D modelling tool that I came across the other day (and it's free!)
What's the first thing you do when you play with something like this? You recreate where you live of course!
If I'm still bored tomorrow, I might have a crack at furnishing the place, including having the right pictures on the walls.
I really did it so I could show my folks what our place looks like without them having to fly over here to see it.
