Stumbled across this ongoing project by artist Alina and Jeff Bliumis which features installations of foam dictionaries used to obscure sightlines, block windows and to physically interrupt daily routines.

Love the way that the installations define how people interact with the space around them and how they have been used to create physical barriers to show the 'fragility of communication' and to draw attention to the 'social and cultural differences that characterize life in New York City'.
