The artist, designer, and jazz musician Walter Giers (1937–2016) is one of the most important exponents of media art from Baden-Württemberg who produced electronic light-sound works in the tradition of kinetic art. In 1969 Giers embarked on making his first non-functional objects out of electronic components. These were objects that offered the spectator a playfully active role: by turning various switches, he or she was able to bring about a sequence of dynamic movements. In 1973 Giers abandoned the tactile principle of consciously spectator-generated movement in the objects he made and started to integrate random generators. As a result the works appeared to evolve a life of their own as impulses set off by the light, sounds or movements around them were translated into optically or acoustically perceptible alterations.The many light and sound sculptures to result from this approach, combining invariably clear outer structures with lyrical or meditative qualities, are intended to set off a range of associations in the mind and emotions in the spectator. Works using light fields serve to link large spaces together; and sound objects, with their acoustic effects, intrude almost aggressively into the display space.
