Boat crew members train on the waters of the Tonle Sap River on the morning of the first day of the Water Festival on November 13, 2016 in Phnom Penh, Cambodia. The yearly three-day Water Festival is one of the most important holidays in Cambodia and celebrates the end of the rainy season and the start of the rice harvesting. The Festival also coincides with the Tonle Sap river reversing course, which it does twice a year. Approximately 2 million people are expected to attend this year's festival, during which 259 boats and nearly 20,000 oarsmen will participate in the races. After a fatal stampede resulting in the death of some 353 people during the Water Festival in 2010, it has been cancelled four times over the past five years, with weather used as an official excuse.

Plants grow on houses in the abandoned fishing village of Houtouwan on the island of Shengshan July 26, 2015. Just a handful of people still live in a village on Shengshan Island east of Shanghai that was once home to more than 2,000 fishermen. Every day hundreds of tourists visit Houtouwan, making their way on narrow footpaths past tumbledown houses overtaken by vegetation. The remote village, on one of more than 400 islands in the Shengsi archipelago, was abandoned in the early 1990s as first wealthy residents then others moved away, aiming to leave problems with education and food delivery behind them.

Ra Paulette is an American cave sculptor based in New Mexico who digs into hillsides to sculpt elaborate artistic spaces inside mountains. Reviewer Martha Mendoza in the Los Angeles Times described the caves he created as shrines, as hallowed places, a “sanctuary for prayer and meditation” while others describe the caves as works of art. The caves are finished with “scallops, molded curves, smooth ledges, inlaid stones, narrow pods and crusty ledges”. His caves attract visitors worldwide.

Mini Amsterdam has launched a promotion campaign for their brand new creation Mini Copper. The idea is that Mini Copper is so small that it could fit in a box. Thus, as part of the promotion campaign, huge cardboard boxes were left in various popular placed of Amsterdam, making it look as if someone has bought a Mini Copper and thrown out the cardboard box it came in. Of course it is simply a commercial; however, it clearly illustrates just how small the Mini Copper really is. This is a perfect vehicle to handle narrow streets and lack of parking space. Truly, this vehicle could be parked just about anywhere! (Photo by JWT)
