I wasted a bunch of time on this, stupidly. I should’ve been writing some stuff I have to hand in on the 2nd, for a class on peer to peer networking, but instead, I modelled where I live in Google Sketchup. Screens of the results are below. It’s not only possible to model the flat I live in, but converting it to show a whole floor or building, and even showing this inside Google Earth is very easy to do. I like it a lot, I shall have to do more of this.
