The Arvada Center’s “Informed Space” is the surprise art exhibition of the summer. And the most rousing. The sprawling spectacle, featuring 30 Colorado sculptors, each with a mind and style of their own, is regional art at its best. The work is elevated but unpretentious, polished yet handmade; caring and daring at the same time. Artists were given a four-square-foot area to show their sculptures.The blue wire in the center is by Deborah Jang.
