We live small, but sometimes we like to dream big. In the "if we had the space for it" category lies Gitta Gschwendtner's Plant Cup planter. Although the giant white glazed earthenware cup is designed to be used for plants, we're thinking that it could also be used in a wittier way (we're still working on that; we feel like we need coffee in that size cup today). And, of course, it could provide hours of entertainment for a cat.
