Carlos J. Gómez de Llarena, The Urban Speaker at the 2010 Conflux Festival. via Alias Arts

There are many “updates” to the traditional Speaker’s Corner, including Monica Sheets’ Free Speech Machine and Daniel Jolliffe’s One Free Minute. What I particularly like about Carlos J. Gómez de Llarena’s The Urban Speaker is the way it uses signage and the semiotics of construction sites to both call attention to the piece and to camoflauge it in the urban environment.
