The saga of Denver International Airport’s colorful, infamous public art program continues. Last week, airport officials unveiled the latest piece commissioned as part of Denver’s 1% for Art program, which routes 1% of any municipal construction budget toward custom art for that project. Forty other site-specific art projects already adorn the airport’s sprawling property. This time it’s “Luminous Wind,” a $350,000 sculpture created by artists Laura Haddad and Thomas Drugan.
