Tobias Rehberger

He has created an idyllic Japanese garden in the middle of Manhattan; Pop-inspired wallpaper consisting of photographs of his organs; a series of Modernist-looking treehouses in a park in northern Germany; and an enormous tanker based on a crude boat that the father of a friend built to escape from Vietnam.

[2] For his art-car series, a project that he began in 1999, Rehberger sent simple sketches, composed essentially from memory, of a Porsche 911 and a McLaren F1 to a manufacturer in Thailand.

[3] Rehberger also spent some time in Cameroon, where he provided native crafts workers with his crude drawings of well-known modernist chairs and asked them to recreate the designs.

[4] On the east side of Madison Square Park in New York, Rehberger in 2001 created Tsutsumu, an elegant Japanese garden made up of a large bonsai tree, a bench and a rock.

[6] In 2013, Riley claimed that a wall-sized, black-and-white checkerboard work by Tobias Rehberger plagiarised her painting Movement in Squares and asked for it to be removed from display at the Berlin State Library's reading room.
