His exhibit, Partly Sunny: Designs to Change the Forecast, showcases innovative and practical environmental design, urban planning, and activism projects that seek to improve environmental conditions. Culture blogger Rhode Island's Future took in Cannon's exhibit and dubbed it "impressive," noting that it features more than 30 projects "that show people how to reduce their impact on the environment from a bike-sharing program in Paris to a Netherlands nightclub that generates electricity from dancing patrons."

If you're in Denver and want to check it out, the exhibit is open from 10 a.m. to 6 p.m. throughout the convention at the Denver Pavilions. Further afield? Check it out here.
