Gus Petro is a Swiss photographer that recently published a neat visualization of the size of the Grand Canyon. He took his pictures of buildings and the Manhattan skyline and used Photoshop to drop them into his pictures of the Grand Canyon. You can see the pictures on Gus Petro’s website and in this Atlantic article which is where I found them.
