Thank you for the comments. This is an amusement park, and the small balls are some sort of a ride. Also, there was a big billiard ball attached to the table (at the bottom of the photo you can see this attachment from the reflection), and it was rotating with a small speed. The ball was shiny, and there was good amount of sun light. So, I tried to take some photos of the reflections. You can even see me at the center of the "world", taking this picture:-)
