A couple in pink pose in Nevada's Black Rock Desert as part of the Burning Man Festival. Each year tens of thousands of people amass in the Nevada desert to take part in what organisers describe as an experiment in community, radical self-expression, and radical self-reliance. One of the principles of the festival is to participate, and people are encouraged to construct pieces of art that, on the sixth and final day of the festival, along with a large effigy of a man, will be burnt in a huge bonfire to celebrate the spirit of renovation.
