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.

In this November 18, 2014 photo, Murshida, 12, sits on the lap of her mother Marjina as the train leaves for their village in West Bengal, at a railway station in New Delhi, India. Six months ago, Marjina stepped off a train in New Delhi with her two children, hoping to find a better life after her husband abandoned them without so much as a goodbye. The family spent their days at a landfill picking through other people’s garbage to find salvageable bits to resell or recycle. After six months of poverty, illness and shame, they returned to that train station in New Delhi, headed back to an uncertain future to their hometown in West Bengal. (Photo by Altaf Qadri/AP Photo)

Cool rider Ace on the back on the motorbike, on January 12, 2015, in Surabaya, Indonesia. A pair of dogs enjoy a bit of bark-and-ride – as they weave through Indonesiaís traffic on the back of a motorcycle. Wearing red-framed sunglasses and a helmet the two golden retrievers happily sandwich their owner on the fast bike. Unsurprisingly, the sight of the docile dogs hitching a fast ride in Surabaya, Indonesia, attracts a lot of attention from onlookers. Ace and Armani have been riding since they were just a few months old and now at the age of three the pair jump onto the bike whenever they think their owner is heading out.
