When I look at this gadget, the chameleon will pops up in my mind. Some of them has the ability to changing color. Just like this unique pen which allow you to scan colors from anything around and instantly use the color for drawing. The color is detected by the RGB Color Sensor inside the pen, then the red, green, and blue inks are mixed together to create the desired color. I hope they will implement and produced this cool gadget later. Brilliant.
