Oh Bauhaus...
"Form Follows Function"
http://en.wikipedia.org/wiki/Form_follows_function
In the late 1910s the two principles of “form follows function” and “ornament is a crime” were effectively adopted by the designers of the Bauhaus and applied to the production of everyday objects like chairs, bedframes, toothbrushes, tunics, and teapots. Some of those forms were refined and purified to such an extreme degree that they became unusable by humans, but generally the Bauhaus still constructively influences the look, feel and function of consumer goods down to the present day.
