If you're not looking for absolute pure precision in your temperature reading equipment, but would like to get an idea of it in a fun and creative way, then check out these cool new Leaf Thermometers from designer Hideyuki Kumagai. They may look like green tree leaves at 68-77° F, but these temperature sensitive paper versions turn brown when the room temperature gets colder and bright yellow when it gets warmer. They come in 2 sizes, large (5-pack) or small (8-pack) and are perfect for scattering around your home or office as functional decor or they recommend creating a wall mural of leaves to show the changing of the seasons.
