Niki de Saint Phalle in the context of "Play park"

A playground, playpark, or play area is a place designed to provide an environment for children that facilitates play, typically outdoors. While a playground is usually designed for children, some are designed for other age groups, or people with disabilities. A playground might exclude children below (or above) a certain age.

Modern playgrounds often have recreational equipment such as the seesaw, merry-go-round, swingset, slide, jungle gym, chin-up bars, sandbox, spring rider, trapeze rings, playhouses, and mazes, many of which help children develop physical coordination, strength, and flexibility, as well as providing recreation and enjoyment and supporting social and emotional development. Common in modern playgrounds are play structures that link many different pieces of equipment.

The Museum Tinguely is an art museum in Basel, Switzerland, dedicated to the work of Swiss painter and sculptor Jean Tinguely (1925–1991). Designed by architect Mario Botta, it opened in 1996 on the banks of the Rhine. The museum holds the world’s largest collection of Tinguely’s works, ranging from early reliefs to large-scale kinetic sculptures.

The museum’s permanent display includes Tinguely’s kinetic sculptures, together with illustrations, photographs, and archival materials related to his life and work. Shortly after the museum opened, Niki de Saint Phalle donated more than 50 works from Tinguely’s estate. The museum also organizes temporary exhibitions that engage with other artists, including Tinguely’s contemporaries and modern practitioners.

Playground slides are found in parks, schools, playgrounds and backyards. The slide is an example of the simple machine known as the inclined plane, which makes moving objects up and down easier, or in this case more fun. The slide may be flat, or half cylindrical or tubular to prevent falls. Slides are usually constructed of plastic, metal, and sometimes concrete. They have a smooth surface called a 'slide bed' that is either straight for the full length or can contain bends. The user, typically a child, climbs to the top of the slide via a ladder or stairs and sits down on the top of the slide and slides down the chute.

In Australia, the playground slide is known as a slide, slippery slide, slipper slide or slippery dip depending on the region. Whereas sliding board is used in the Philadelphia area and other parts of the Mid-Atlantic.

Nouveau réalisme (French for "new realism") is an art movement founded in 1960 by the art critic Pierre Restany and the painter Yves Klein during the first collective exposition in the Apollinaire gallery in Milan. Restany wrote the original manifesto for the group, titled the "Constitutive Declaration of New Realism," in April 1960, proclaiming, "Nouveau Réalisme—new ways of perceiving the real." This joint declaration was signed on 27 October 1960, in Yves Klein's workshop, by nine people: Yves Klein, Arman, Martial Raysse, Pierre Restany, Daniel Spoerri, Jean Tinguely and the Ultra-Lettrists, Francois Dufrêne, Raymond Hains, and Jacques de la Villeglé. In 1961 the aforementioned nine were joined by César, Mimmo Rotella, then Niki de Saint Phalle and Gérard Deschamps. The artist Christo showed with the group. It was dissolved in 1970.

Contemporary with American pop art, and often conceived as its transposition in France, new realism was, along with Fluxus and other groups, one of the numerous tendencies of the avant-garde in the 1960s. The group initially chose Nice, on the French Riviera, as its home base since Klein and Arman both originated there; new realism is thus often retrospectively considered by historians to be an early representative of the École de Nice movement.
