I came across a page full of pictures that play with perspective and scale:

The artist's page gives you thumbnails that don't always show the cool part of the picture. This fan page has a whole pile of them all one after another to get you started seeing how they work. There are more at the artist's page though, plus instructions on how you can buy prints, so even if you start at the fan page, you should end up at the artist's page. According to Wikipedia and another article I found recently, he's a Canadian who illustrates children's books and wins awards for it. That explains all the snow, moonlight, and autumn leaves, I guess .
