The inaugural Desert X art festival is underway in Southern California, where visitors are using Instagram to share images of installations including an entirely mirrored cabin and a seemingly infinite tunnel into the earth.
The new art festival is taking place in the desert of the Coachella Valley, which hosts one of the world's largest music festivals each year.
Desert X includes 16 projects dotted around the valley, created by local and international artists.

Here is a selection of the best artworks, most of which are on view until 30 April 2017:
