The cre­at­ive minds at mini­W­IZ recently deb­uted the POLLI-Brick, a recycled poly­mer bottle that can be inter­locked to build an incred­ible array of struc­tures. Made from recycled PET bottles, the light­weight bricks offer excel­lent acous­tic and thermal insu­la­tion and can build any­thing from fences and roofs to pots for plants, sky­lights and beau­ti­ful walls of light.
