An electronic brush promises to give artists more control of their digital work. “Unlike other painting programs that allow artists to pick up colors from a limited computer palette, I/O Brush lets people paint with colors and textures that might come from, for instance, a piece of fruit, a favorite shirt, a memento from a trip, a teddy bear or garden flowers. The brush contains a microphone, a miniature video camera, and sensors and is wired to a computer that runs a touch screen. An artist picks up “ink” from her environment by lightly brushing over the desired object.”
