The �I/O Brush� is a drawing tool that not only releases ink, but also captures ink from the artist's immediate environment. Like an old pen or a paintbrush, it functions as both a tool to pick up ink and a tool to draw. But instead of picking up ink or paint, the I/O brush picks up color, texture, and movement from any surface or material. It looks and feels like a real paintbrush, but embedded inside is a tiny video camera with a special light, and a touch-sensitive Wacom pen. The artist may brush any surface outside of the drawing canvas (cloth, skin, her friend�s long hair waving with the wind), and the fiber optics on the brush light up to indicate that it's picked up that surface, and the artist can then draw on the canvas with the special ink.
