World Imitation is known for their publication of xeroxed zines, a series of collage-based booklets focusing on art exhibitions, happenings and events of the times, and mail art exchanged with other contemporary artists. These publications were sold at punk venues and record shops and were circulated locally and internationally. World Imitation eventually became a production company, forming the band, Monitor, and released a number of records under the Monitor name, and later The Tikis. As a member of Monitor, Thomsen played synthesizer and keyboards. He was also a member of the group, Solid Eye which was formed in 1992.
