This photo just blew my mind:
From Britain's Daily Mail:
"These bizarre images show a gigantic cloud of dust billowing over an African city - just like a scene from the movie The Mummy. The dust storm - known as a "Haboob" - gathered over Khartoum, the capital of Sudan in north east Africa yesterday. It lasted for about two hours, carrying dust and sand from the Sahara across the city. Haboobs - which are a type of seasonal storm - are formed in summer months."
