De Stijl
De Stijl was influenced by Cubist painting as well as by the mysticism and the ideas about "ideal" geometric forms (such as the "perfect straight line") in the neoplatonic philosophy of mathematician M. H. J. Schoenmaekers. The De Stijl movement was also influenced by Neopositivism. The works of De Stijl would influence the Bauhaus style and the international style of architecture as well as clothing and interior design. However, it did not follow the general guidelines of an "-ism" (e.g., Cubism, Futurism, Surrealism), nor did it adhere to the principles of art schools like the Bauhaus; it was a collective project, a joint enterprise.
