Clean, green, fun. We recently blogged about the toxic nature of your run-of-the-mill PVC shower curtain. If you use a shower curtain and retain any fondness for your Schoolhouse Rock days, the products of a company called Smart (simple memory art) will bring a smile to your wet face. Smart's MO is to "inspire both children and adults to learn and to laugh in unexpected places." Like the bath. Smart's silkscreened curtains are 100& EVA, and are bedecked with cartoon diagrams from basic science, like a recap of the solar system or the periodic table, to help you soak us some knowledge. The aesthetic is colorful, youthful, cheerful, and at $32 each, you can change the lesson plan every so often. Available here.
