Denver's Mayor, John H. Hickenlooper, announced Dialog:City, an event converging art, democracy and digital media that will involve 10 site- specific art installations in neighborhoods throughout Denver from Aug. 21- 29.

World-renowned artists will come together to create a series of innovative commissioned works in conjunction with local organizations and students.

Some descriptions of the artists' projects follow:

Charlie Cannon and students from the Rhode Island School of Design's Innovation Studio will present visual designs in the categories of buildings, food, energy, "greening" cities, water and transportation. Focusing on what actions can be taken now, Partly Sunny: Designs to Change the Forecast includes collaboration with GreenPrint Denver, Rocky Mountain College of Art + Design, and Green Order.

Minsuk Cho's architectural Pavilion for Public Discourse will be installed in City Park. This pneumatic structure will levitate, creating a sculptural canopy. Events, symposiums and parties will assemble at this new model for a public square.

Hindsight is Always 20/20 is R. Luke DuBois' presentation of high- frequency words from presidential State of the Union addresses. The words have been translated into the visual hierarchas light boxes in front of the Denver Performing Arts Complex.

Lynn Hershman's DiNA is an artificial being running for president. DiNA is fully interactive; audiences will be able to ask her questions about her issue platform. Artificial Intelligence is better than no Intelligence at all brings cutting- edge technologies and the political race into a convergent and dynamic demonstration at The Lab of Art and Ideas at Belmar.

Daniel Peltz will present his new work, Participatory Democracy and the future of Karaoke, in which Peltz transcribes public addresses by presidential candidates in the 2008 election into a karaoke format to be presented and performed at bars, clubs and restaurants across Denver. D.J. Spooky, a.k.a. Paul Miller, will perform Terra Nova: The Antarctic Suite at the Ellie Caulkins Opera House. In keeping with the Convention's green theme, his work is a multimedia experience that samples from his recordings of the sights and sounds of ice breaking and melting in Antarctica.

The spurse collective will create a series of walking tours in which audiences can listen to sound based upon existing seismic and geographical data sets for Denver specifically where audiences will travel.

Participation in Dialog:City will be open to all citizens of Denver and to visitors from around the world. While the exhibitions will be concurrent, each will have a dedicated opening enabling the public to attend every event. Dialog:City will be the first program of its kind at a party convention.
