Stripes are two different art designs, one located in Armonkallio and the other in Santalahti. They are part of the Tampere tunnel concrete noise barriers art designs by six visual artists. Visually, both designs by Soini share the use of stripped form, realized three-dimensionally in graphic concrete, that connects them to the art in the huge ventilation pipes of the tunnel.

The work in Armonkallio aims to support the sense of street space in Soukanlahdenkatu. It reminds of basement floor walls of the street. The surface, mainly coated with paint, include a rhythm of stripes made of wedge-shaped forms within which both smooth and rough washed concrete finishes are found. The asymmetrical surfaces, that change in appearance according to the direction of approach, are available especially to pedestrians when passing by the work. The same idea was applied in the painted additive parts, too.

The work in Santalahti strives to adapt itself to the overall landscape of the area. The work consists of parts resembling navigation marks. The surface is created as a combination of black aggregate and stripes made of trough-like depressions in it. The depressions are finished with metallic paints creating reflections and illusory shapes. The materials used are sensitive to changes in light conditions. Thus, the changing appearances of the work depending on the lighting. The phenomenon can best be observed from a moving car.
