A “soft wall” that uses a clear polyethylene film woven with translucent PET mats as the main growing medium. The sheets can be stitched together to create open pockets for vegetation (translucent/opaque) as well as closed pockets for water (transparent). Depending on the type of movement, the expansion of the pockets can be manipulated by mechanical pin joints or with elastic string.
