The Creativity & Cognition Conference series began in 1993 and has evolved into a lively multidisciplinary event combining research and practice. Rigorous research is expanding as theoretic foundations are emerging and goals become more well-defined. Successful practice manifests itself in a growing array of creativity support tools for discovery and composition by software and other engineers, diverse scientists, product and graphic designers, architects, new media artists, musicians, educators, students, and many others. We believe that deeper understanding of creative processes and improved support tools can make more people more creative more of the time. Creativity & Cognition 2007 is focused on theme of cultivating and sustaining creativity: understanding how to design and evaluate computational support tools, digital media, and socio-technical environments that not only empower our creative processes and abilities, but that also encourage and nurture creative mindsets and lifestyles.
