Tilt-shift Photography 

Tilt shift lenses focus on a single part of the photo and blur the surrounding area to create an optical illusion of miniaturized scenery (like your uncle’s train set). The blurred outer edges trick the eye into perceiving everything in the unblurred parts as miniature. Real tilt shift lenses are quite expensive, but a similar effect can be achieved by using Photoshop after you take the photo.
