These brilliant acoustic Hexagon wall tiles created by Form Us With Love are a wood/wool/cement product made in conjunction with the Swedish company Traullit. The tiles are environmentally friendly and use wood slivers mixed with water and cement in the manufacturing process. They’ll instantly reduce echo in your empty space and bring a fresh new graphic look to your wall space.
And I also found these amazing concrete floor tiles by IVANKA which can be had in almost any possible color.
