This solution gives you the freedom to create a surface with repetitive or random patterns. Troldtekt puzzle is made up of square acoustic panels with four equal sections. Three of the four sections have diagonal, vertical or horizontal grooves cut.
You can continue the pattern from panel to panel, and vary the effect by offsetting the rows or turning some panels 90, 180 or 270 degrees. It is entirely up to you which ‘puzzle’ is presented on the surface.
