Contemporary genres

Some modern sculpture forms are now practiced outdoors, as environmental art and environmental sculpture, often in full view of spectators. Light sculpture, street art sculpture and site-specific art also often make use of the environment. Ice sculpture is a form of ephemeral sculpture that uses ice as the raw material. It is popular in China, Japan, Canada, Sweden, and Russia. Ice sculptures feature decoratively in some cuisines, especially in Asia. Kinetic sculptures are sculptures that are designed to move, which include mobiles. Snow sculptures are usually carved out of a single block of snow about 6 to 15 feet (1.8 to 4.6 m) on each side and weighing about 20–30 tons. The snow is densely packed into a form after having been produced by artificial means or collected from the ground after a snowfall. Sound sculptures take the form of indoor sound installations, outdoor installations such as aeolian harps, automatons, or be more or less near conventional musical instruments. Sound sculpture is often site-specific. Art toys have become another format for contemporary artists since the late 1990s, such as those produced by Takashi Murakami and Kid Robot, designed by Michael Lau, or hand-made by Michael Leavitt (artist).
