Bangkok, Thailand

Bags of cow dung are thrown at the Thai architect Duangrit Bunnag at the Mirror gallery in response to developments in Thai politics. Duangrit invited the public to watch him keep his promise after he tweeted: ‘If the Pheu Thai party joins hands with the Palang Pracharath party, I will allow people to throw shit at my head’
