Ahhh the decorative pervious paver. These are available for a sand set application that may incorporate small pebbles, grass or just left open. I think these would look great inserted as a deco into a large area that has smooth Roman Pavers or also used as an exterior entry area in rural setting where shoe soles may need to be cleaned. These are still prototypes but with the help of public's interest this may evolve into many types of designs and may even be used as a screen wall where light can be manipulated to create an atmosphere like no other
