For 10 points, identify this Futurist artist who created Riot in the Galleria and Unique Forms of Continuity in Space.
This artist featured a background of blue and yellow splotches on a green wall in one of a self-portrait "with paintbrushes". Another one of his paintings is dominated by the word "CAFF" which appears just above several flashes of bright yellow and another painting prominently features the number "6943" in between industrial images including a locomotive and a radio tower. This artist included The Farewells in his States of Mind series, but he may be better known for sculpture that depicts an armless figure moving dynamically.
