'Happiness and sadness always coexist': Ai Weiwei's first virtual reality artwork Omni

Omni fuses together two films the artist has made, immersing viewers in a jungle full of elephants first and then in a refugee camp in Bangladesh. 'I feel a lot of positive things about humanity even in the worst conditions. I don’t want to show that there is just sadness. Happiness and sadness always coexist,' Ai says. The video was produced in collaboration with Acute Art, who work with artists to make virtual and augmented reality videos.
