Artomatic is a multi-week, multimedia arts event held in the Washington metropolitan area of the United States. It was founded by Washington, D.C. artist and arts activist George Koch.[1] The non-juried, open event has provided a forum for artists of all types (visual, performance, and literary) and abilities (from novice to professional). There are also arts education and professional development workshops and discussions. Events were held from 1999 up to 2017 at intervals from one to three years, depending upon the availability of a site. Unable to have in-person events due to the COVID-19 pandemic, an online event was held in 2020. The organization has remained active in the local arts community.
