In his paintings and sculptures one can find, passed through a severe analytical filter, elements of popular culture, especially the ones that preserve the attitude of the anonymous creators towards existence. "As the masters among the people" wrote Petru Comănescu - "Mihai Olos creates not only focusing his mind on himself, but also on the world that he belongs to and therefore he’s got the odds on his side to be equally Romanian and universal, to be traditional and modern, with a very personal note as an intellectual-artist, as a master-poet." One of the motifs that concern him is the "spindle with jingles" (jingle bell) - an object from the peasant household industry, being an ingenious mixture between the functional and sculptural fields. From the modules of this work, he develops original spatial constructions. In painting, the constructivist principles are characterized by the analysis of the motifs that take place, by repetition, on the whole surface of the painting, therefore animated by optical elements. As a complex personality, of a rare spiritual mobility, Olos is also an author of poetry, the initiator of some happenings: The Gold-Wheat Event at the Herja mines, Below the mine’s ground, 1972; Earth, Cuhea, 1973; The Visual Communication (Dedeochiul), Giessen, 1978; A Statue Walks through Europe: I. Meeting Gaudi (Barcelona); II. Meeting Beuys (Düsseldorf), 1978. Furthermore, he is the author of some monumental works with kinetic programme (120 m2) at "Dacia" Movie Theatre in Baia Mare.
