These are pretty and amazing, so pretty amazing. I have an app, as we all do, but this one I have is called Small Planet and it creates worlds from pictures taken with my phone, impressive. Then again there are these images which go far beyond my clever little app.
As see on The Guardian Website The stereographic projection technique was used to convert aerial panoramas of cities including Paris, Sydney, Shanghai and Chicago into mini-globes. 
Paris, FranceThe Champs-Élysées
The 360-degree aerial panoramic photos were taken for AirPano, a Russian not-for-profit project created by a team of enthusiasts

The original photograph was usually taken from a helicopter, although sometimes the team used a plane, hot air balloon or drone
