Tokyo-based designer Duncan Shotton, known for his whimsical functional objects like the magnetic cloud keyholder and his Lochness monster pins, just launched a Kickstarter Project for a new kind of pencil that makes rainbows when you sharpen it. Each pencil has a 6-layer rainbow core of recycled paper (not wood) and either a white or black exterior. Shotton says the pencils will ship before Christmas.
