The document summarizes and discusses several kinetic artworks and artists. It describes Signature by Tim Hawkinson, an artwork that endlessly produces facsimiles of the artist's signature on paper. It also mentions the 1985 performance piece by Chris Burden called "Samson" that could theoretically destroy a building if enough visitors cause the mechanical system to expand. It provides descriptions of kinetic sculptures by Charles Jencks, Rebecca Horn, Allan Wexler, Theo Jansen, Arthur Ganson, and C辿leste Boursier-Mougenot that incorporate mechanical elements and movement.
