There is a photoshop technique that I have been fascinated with for some time called "Tilt Shift" It is a process where you take a photo (usually a landscape of some sort) and give it an effect of being a miniature scale model vs a large reality scaled landscape.
While on the Scott Kelby Worldwide Walk, I took a photo that when I viewed it set off the alarms..."MUST TILT SHIFT"!!! lol...this was the end result.
The effect can be achieved with a photograph with a large depth of field, (artificially creating a small depth of field on your focus plane. Your focus area stays sharp, everything else is blurred slightly out of focus. Wikipedia has a couple great links on "Tilt Shift":
