Black squares

Malevich's "Black Square" gets 67,000 hits on Google Images (it's the one in the middle...). It was part of the 1915 Futurist exhibition -
As homage to Malevich, Gregor Schneider made "Black Square", a 14-metre cube, inspired also by the Kaaba in Mecca. He won the Golden Lion at the 2001 Venice Biennale for the exhibition of his childhood home, Totes Haus u r (Dead House u r), but in the 2005 biennale wasn't allowed to install "Black Cube" in St Mark's Square - it might offend Muslims. In 2007, having been rejected by Berlin, it was exhibited in Hamburg, and welcomed by Germany's only ayatollah, who lives there. Read more about it here and an interview here.

Another artist using the "black square" theme is Gillian Carnegie. She was nominated for the Turner Prize in 2005. The Tate website says:
"Carnegie takes this complex interplay between subject and medium to an extreme in her series of black paintings. These night-time woodland scenes, constructed almost in relief from thickly applied paint, refer explicitly to Kasimir Malevich’s infamous Black Square painting of 1913. But Carnegie offers a retort to the macho, modernist tradition of the monochrome by planting a landscape at its heart. Despite her dingy palette and quiet imagery, her works have a charged energy that brings attention back to the personality manipulating the paint. "
