Mach's artistic style is based on flowing assemblages of mass-produced objects. Typically these include magazines, vicious teddy bears, newspapers, car tires, match sticks and coat hangers. Many of his installations are temporary and constructed in public spaces

In the early 1980s Mach began producing smaller-scale works assembled out of unstuck match sticks. These mostly took the form of human or animalistic heads and masks, with the coloured tips of the match heads arranged to construct the patterned surface of the
