Nice. Some kind of explanation would be helpful, though. Apparently the size of the circle is related to the mass of the meteorite, and color is density of circles. But it took me a while to figure that out. Also, what happened in Oman? EDIT: Wikipedia says, "The central desert of Oman is an important source of meteorites for scientific analysis." Possibly meteorites are just easier to find there, due to properties of the terrain. Perhaps meteorite hunting is a popular sport/business, too?
