Gambiocycle is a mobile broadcast unit. It is a modified cargo tricycle containing electronic gear for interactive video projection and digital graffiti in public spaces. The Gambiocycle was developed as part of Gambiologia, which is an open-source art movement based on the fusion between technology and “gambiarras”: the Brazilian cultural do-it-yourself practice of solving problems in alternative ways or giving unusual functions to objects, a slang word for technical makeshifts and kludges.
