Berlin-based artist Hans Hemmert (famous for his work with balloons) threw a party where guests wore shoe-extenders to make them all the same height of 2 meters. Aside from bringing the partygoers all to a common eye level (and eliminating the awkward postures of party talk between the tall and the short), the gathering is lent an infographic nature by the shoes: all made from blue foam, the person's real height is read in the visual uniformity of the sole instead of at the head—like a walking bar graph.
This (completely underpublished) project, entitled "Level," is from 1997, produced for the Personal Absurdities show at the Galerie Gebauer Berlin. Finding it now, in 2010, I can't help but read it as a design event, getting directly at the basic qualities that shape our interactions with others—what does it mean when we all share one height?
