The exhibition , created by artist Matthew Dehaemers , features Dex telephone directories built as sculptures that pay homage to and recreate various tools , buildings and more - all of which have ties to communication . For example , one facet of the exhibition features a " telethon room , " built out of directories , where a team of volunteers is using the Dex white pages directories to reach out to Omaha residents . The team intends to make 100,000 phone calls to individuals throughout the city , offering affirming thoughts and asking simple questions that ties the individuals to the local community . The exhibition is scheduled to run until May 16 , 2009 .
