Wow, how long did that take to build? How did you take the pictures with the circular crop on them?
Check out the other house synth that was just uploaded (http://photosynth.net/view.aspx?cid=e328ce51-32ea-4606-8f77-3cd003925339
). Is this just coincidence?
Also, you can try walking around the house instead of spinning it to get a better synth. The synther assumes the entire world is stationary and can get confused when the subject moves differently than the background.
