Art collector Charles Saatchi has announced he will give his gallery and $37 million worth of art works to Britain. They include Tracy Emin's messy bed, Grayson Perry's explicit pottery and a room full of engine oil, many Damien Hirst and works by China's Zhang Dali and Feng Zhenghie, and India's Jitish Kallat. The 70,000-square foot Saatchi Gallery will be renamed the Museum of Contemporary Art, London.
