Long-tailed mayflies (Palingenia longicauda) at Tisza river near Tiszainoka 135km (84 miles) southeast of Budapest, June 23, 2013. Millions of these short-lived mayflies engage in a frantic rush to mate and reproduce before they perish in just a few hours during “Tiszaviragzas” or Tisza blooming season from late spring to early summer every year.

Artist Matthew Albanese creates amazing miniature landscapes made from sugar, chocolate and even bits of ostrich in his living room. All the models were painstakingly recreated in his living room, which he uses as his studio. Each gruelling piece can take up to as many as 700 hours to complete.

An American inventor has built a unique upside-down racecar – and successfully taken it on a 24-hour spin around the LeMons track. Jeff Bloch – also known as SpeedyCop – built his upside down 1999 Chevrolet Camaro by combining it with a decrepit 1990 Ford Festiva. To enter the latest LeMons race the car had to cost less than $500, which Bloch achieved by picking a Festiva model with a worn-out 1.3-litre engine and more than 300,000 kilometres on the clock.

It has taken 3,000 hours and 34 years to make – but the results are incredible. Artist Scott Weaver has created a huge but incredibly detailed model of San Francisco using 100,000 toothpicks. The work entitled Rolling Through the Bay also doubles as a marble run. Ping pong balls dropped on several ramps at the top of the model follow several “tours” through the city. They pass matchstick replicas of sights such as Alcatraz, Fisherman's Wharf, the Golden Gate Bridge and the city's trademark terraced houses on steep hills.

Joseph Ford is a 39-year-old photographer from Brighton, UK. He creates images seamlessly camouflaging people into backgrounds using knitwear made by Nina Dodd. It can take Dodd, 51, up to 40 hours to knit one item of clothing. This image of a man posing in knitwear, camouflaging into tiles of the steps and wall, is a personal favourite of Joseph’s.

For theatregoers in St Petersburg, Nacho Duato's “The Nutcracker” demonstrates the global appeal of a Christmas classic. When the curtain rises at the Mikhailovsky Theatre, among the oldest opera and ballet houses in Russia, it's the culmination of hundreds of hours of toil and sweat by dancers, costume makers, set designers and musicians playing the famous score by Pyotr Tchaikovsky.

The Tibetan night sky was captured in these beautiful images showing the stunning buildings and statues in the Himalayan mountains. Grey Chow, 33, traveled for two hours to get to the Spiti Valley to capture the starry backdrop along the isolated, deserted roads. The senior project engineer was able to take amazingly clear images thanks to the limited amount of pollution at the 4,500-foot (1371m) altitude. (Photo by Grey Chow/Caters News Agency)
