My colleague Wilfrido "Willie" Cruz and I began using Mark Williams' Ten Lenses: Your Guide to Living and Working in a Multicultural World for staff development in 2006.  We have prepared many different versions of the training over the years, which has sometimes included monologues, skits, video clips...The various versions have taken anywhere from 30 minutes to 3 hours to present.  This particular version was created to give an overview of Williams' theory at the NAFSA Region VI conference, held during the first week of November 2019 in Columbus, OH.
