At the press preview for the North American International Auto Show, I snapped these difficult-to-shoot pics of what I am calling waterfallvertising. At the Jeep display, the waterfall is actually streamed in such a way that the water 'prints' the JEEP logo, stars, stripes and a picture of a jeep. This is NOT done by shining light onto the waterfall. Rather, the water is carefull streamed.
The technology is similar to the Pixel Roller Paint Roller and the GraffitiWriter Automated Graffiti Robot. The latter is a remote control truck that paints text like a dot matrix printer.
