One of my favorite shots I've ever taken was back in Vietnam, circa February 2004. The aerial view of Hanoi was taken with a 4MP camera and has appeared in a number of print magazines and online publications.
I always thought it would look neat as a fake 'miniature' image, so I took the original and threw it into the online Tilt-Shift Maker tool. It is remarkably easier to do online than in Photoshop.
My original post of this image appears here just in case you wanted the reference.
