I read an issue of Art in America -featuring the amazing work of Janine Antoni on the cover and discovered a past work of Antal Lakner: home transporter (from the passive working devices series).
Skewering a vain leisure society that “labors” pointlessly on exercise equipment, Lakner designs workout machines like the “Forest Master” (a saw) and the “Home Transporter” (a wheelbarrow). Each is accompanied by a didactic photo of a worker using the prototype tool.
I find this work actually very marketable as a neat idea for making fitness centers more fun! I know it is not the point and the work is remarkable, but it is also an amazing interface design for transforming fitness centers. Instead of trying to hook up a rowing machine to a virtual boat in a video game, why not connecting the actions with meaningful activities!
