The neo-avant-garde artist group Pécs Workshop (Pécsi Műhely) grew out from this studio, co-founded by Halász, Károly Kismányoky (1943–2018), Sándor Pinczehelyi (1946) Ferenc Ficzek (1947 – 1987) and Kálmán Szijártó (1946) in 1968 (formally in 1970).
[7] Halász's frequent journeys, the constant experience of transition, and the radically different possibilities and perspectives of art in West- and East-Europe led to the creation of portable and evanescent alternative "museums".
[8] Whatnot Museum (1972) consists of a shelving unit with jam jars, resembling a pantry, with reproductions from Kazimir Malevich's Black Square to Robert Smithson's Spiral Jetty and Halász's own works.
"[10] Inspired by the writings and the works of László Moholy-Nagy, he started to experiment with photography and lightboxes, which led to the idea of TV object, a geometrical composition of two intersecting cuboids from steel, fixed on a television screen.
[12] Accordingly, Halász experimented with unusual ways of using television, from painting over his face on the monitor with the help of a closed-circuit set-up to sitting cross-legged inside the empty TV cabinet.
[15] In his Open Geometry series, from 1987, he juxtaposed elements of neo geo stripes and dots with his photographs, mainly depicting body parts of people from ethnic minorities.,[16] while some pieces from the Monolith Structures were combined with monochrome columns and mundane objects, such as chairs and baskets.
