I'm not convinced either. Look at the first row or two of grey houses in the second image. They have pink tops and front fences... Also, in the top left corner of the second image, what is going on with the oragnge tops? Maybe its just the resolution of the picture but it doesn't quite look right.

Oh, wait. I see, the "grey houses" are still being built. They just haven't finished painting them. Nevermind me.

With a remote fill it's just as easy to fill a propane tank on the roof as a fuel oil tank in a basement and a lot more sensible. After all a leak would just disperse harmlessly rather than filling your basement with toxic waste.

Looking at his website all his pictures have that flat colour crisp look to them. I wonder if it's a comination of a cheap digital sensor or film stock and some heavy handed photoshopping.
