These are some so-called tiny planet (or little planet) photos of Washington DC's landmarks. They're real photos—not generated graphics. They start as a 360-degree spherical image and then use software that ramps up the ultra-fish-eye distortion.

How These Were Made
Basically, these start with an equirectangular photo that's used for a 360-degree spherical panorama. They're then processed using software that can manipulate the distortion.
I have more about how they're made here.
