The PSU Littman and White Galleries have a small budget and a rotating cast of student curators. That has sometimes produced some excellent shows. Nia Musiba, from the PSU graphic design department, has a show with bright colors, I'm the Main Character: Radical Dreaming and Art for the Masses. You can learn more about her at https://www.pdx.edu/arts/news/graphic-design-student-featured-opbs-oregon-art-beat.
