Miniature
I really enjoy this stuff.
Many years ago I designed a large mural (in Photoshop) that was supposed to look like a bad movie miniature. TiltShiftMaker does it automatically. Or here’s instructions on doing it yourself.
And when I was a kid, my Uncle John had made the coolest train platform for under his Christmas tree. In it he employed his own take on HO scale suburban zoning – with a detailed downtown, country farms, residential section (in the hills, by a lake) and two circular tracks linking everything.
All the images shown are real, just TiltShifted into looking fake. More here.
