The Blunderwood Portable by the Cat and the Cockroach Collective (2015)
The Cat and the Cockroach Collective, a group of Boston-based artists, built a giant 24:1-scale replica of a 1927 Underwood Portable typewriter.
During the day, it displayed a Archy and Mehitabel poem; and at night, the paper changed to a projection screen so that participants could type their own messages. At the end of Burning Man 2015, the structure was burned.
