Japanese designer Hideyuki Kumagai has created a paper, leaf-shaped thermometer that changes color depending on the temperature. The ‘Leaf‘ stays a natural green color if it’s warm, turns brown if it gets cold, and turns yellow if it becomes hot.

The nature-mimicking device also has a small seal on the back so you can attach it to surfaces or objects in your home or office. The thermometer is available in either a pack of five large leaves (2.6 x 6.6″) or eight smaller ones (1.7 x 4.4″) for $36.
