Ever wish you could have that tool in graphic editor programs that lets you change your drawing color to whatever you click on, but in real life? Now you can with the Scribble Pen. Just touch one end to the color you want, then write with the other end in that color. Probably not a tool for everyone, but the art teacher in me loves this idea. Basically, it is a small scanner on one end, and set of ink tubes on the other end that allows the pen to create a wide range of colors. There is a version that works with paper, one that works with tablets, and one that works with both. Of course, the price is pretty expensive (looks like retail prices will be between $200-400), and you will have to be constantly replacing the ink. The ink is lightfast and water-resistant, so it won’t fade away – but that means it will probably cost more. Still a cool idea that the artist in me is drooling over.
