In pictures: Art in the absence of Ai Weiwei

An art work entitled 'Forever Bicycles' by Chinese dissident Ai Weiwei at the Taipei Fine Art Museum in Taiwan. The installation of 1,000 identical bicycles is part of a new exhibition entitled 'Ai Weiwei Absent', a reference to the travel ban Chinese authorities have placed on the artist since releasing him from an 81-day detention earlier this year.
