Along with teaching at both the University of Utah and BYU, Magleby was commissioned for several historic events. He created the first Cultural Olympiad poster for the 2002 Olympics and he also designed a carving for the Governor's Mansion for the 100th anniversary of Utah. He also designed the Wave of Peace poster, commemorating the 40th anniversary of the bombing on Hiroshima.
In 2008 McRay (Mac) retired from his professorship at the U of U. Since 1987 Magleby has been teaching students how to be creative. He told them, "Being creative is risky; however, where the risks are great, the rewards are greater."
In April and May 2012 Magleby's art was featured in the Covey Center for the Arts exhibit Seasons in the Rockies: Landscapes by McRay Magleby.
