The pair have actually gained something of a reputation for their ingenious design machines; this past fall, Vienna’s MAK museum commissioned one for a group show revisiting the ideas behind Adolf Loos’s Ornament and Crime. The result was this cake-decorating contraption, which allowed visitors to — at the push of a button — pipe icing onto a cake in a Spirograph-like pattern, in effect asking them to decide at what point too much embellishment was enough.
