Joey Roth recently released a series of planters made from naturally porous, unglazed earthenware that lets water seep through the center column and into the soil. He states on his website that they are inspired by Olla, an ancient irrigation tool that famers still use to conserve water in arid climates.
These planters definitely look so much better than the plastic ones, and aesthetically so much more interesting than the traditional terra cotta planters.
Joey Roth also has a set of ceramic speakers that are also very interesting looking.
