Lucius Burckhardt, the founder of the Faculty of Arts and Design at the Bauhaus University once stated: “Design ist unsichtbar” (Design is invisible), referring to the often overlooked implications of the socio-economic structures we create intentionally or serendipitously. Bill Buxton sums up this notion quite nicely:

“Ultimately, we are deluding ourselves if we think that the products that we design are the “things” that we sell, rather than the individual, social and cultural experience that they engender, and the value and impact that they have. Design that ignores this is not worthy of the name.”   —   Bill Buxton
