What about a colorful approach : A little square which is white for 0, black for 1, and taking a scale of gray colors for intermediate values. You'd ajust it the same way as a knob, pressing the mouse button and going up/down, or with the mouswheel. It wouldn't remind the user of any physical equivalent, but it would better suit the digital interface. With a hue scale (HSV color model), instead of a gray one, the visual impact could be pretty efficient, though it would require some practice to get used to it. -- og
