Expect the unexpected
There is a very logical reason why a grown man would be photographed wearing only a pink ballet tutu.
That man, US photographer Bob Carey, started the Tutu Project in 2003 as part of a fund-raiser for Arizona's ballet company. Soon after, his wife Linda was diagnosed with breast cancer. Seeing her husband in the tutu made her laugh, so he continued the photo series.
Carey can be seen in his custom-made tutu in more than 110 photos. He sells individual prints through his website to raise money for other breast-cancer patients.

New trend on the web
Amazon rainforest on Google Street View
World Forest Day was on Wednesday, did you know? To celebrate, Google Maps is taking you on a trip through the Amazon rainforest in Brazil - and you don't even have to leave home.
There's no doubt Google Street View is a great tool to find destinations, especially if you're bad with maps. It's also good for checking out tourist sites that are too expensive or far to travel to.
Google sent a team to the Amazon Basin to collect images of the rivers, forest and communities in the Rio Negro (or Black River) Reserve. The result is a virtual boat tour through the forest and 360-degree views of nearby sites. You'll be able to 'walk' through the lush forests and see unusual plants and animals. You'll get to 'ride' along the coast and see how vast and wonderful the forest is.

Meeting the President of the United States is an exciting occasion for anyone. But for one deaf university student, it was unforgettable.
Stephon, 26, who was born deaf, got more than a handshake at an event in Maryland. Barack Obama was making his way down a line of attendees, greeting each individual, when he reached Stephon. The student used sign language to tell the president: 'I am proud of you.' Obama paused for a second and then signed 'thank you'.
Stephon could not believe the president could read sign language. He posted a video on YouTube recounting his once-in-a-lifetime experience. The White House also tweeted about the encounter (@BarackObama).
