Willem Witsen (13 August 1860, Amsterdam - 13 April 1923, Amsterdam) was a Dutch painter and photographer associated with the Amsterdam Impressionism movement.
 He was born in a wealthy ruling-class family, dating back to the governing families of the 17th century, of whom Cornelis Jan Witsen and his son Nicolaes Witsen were members.
 He studied at academies in Amsterdam and Antwerp.

The Beijing East Village () was an avant-garde artistic community of the early 1990s located in the eastern part of Beijing, just past the Third Ring Road on what was then the city's margins.
 It was formed in 1993 when a group of like-minded artists took up residence together in a "village" of low-quality migrant worker housing, fixing at the entrance a handwritten sign.
 Their community's name was inspired by the East Village of Manhattan, with which they felt an affinity in their experimental aesthetics.
 Only the year after its founding, following the arrest of Ma Liuming for cooking naked in a courtyard, the community was closed by the police, though former residents continued to collaborate.
Curlew Camp was an artists' camp established in the late 19th century on the eastern shore of Little Sirius Cove at Mosman in Sydney.
 It was home for some years to several leading Australian artists, such as Arthur Streeton and Tom Roberts of the Heidelberg School, and it was from here that some of their most famous paintings were created.
 Today the site is still in its natural state and the Mosman Council has built a foreshore walk called the "Curlew Camp Artist's Walk" which traces the journey that the residents of the camp followed when they disembarked from the ferry at Musgrave Street Wharf and returned to the camping site.
 The walk starts at South Mosman Wharf (then Musgrave Street Wharf) and continues along the harbour's edge for 1.6 km until it finishes at Taronga Zoo Wharf.
