You have an acre-sized fountain which is connected to a television feed. Each jet is electronically linked to a set of pixels. They bump up in relation to the image. That's it.

To be viewed as a moving image, there at least has to be a apparent difference in brightness or luminance of each of the jets. How would the height of the jet translate into an image? |

You'd be limited by the water's momentum. The video would be very slow, as each "pixel" would have to shoot up then fall down. |

I had a similar idea, but it involved lighted balloons. I didn't post it because, well, who could see it? Astronauts, I suppose. |

The fountains could be lighted from underneath... |

Control the valves fast enough and get a news ticker that looks like a speeded up introduction to an episode of Star Wars flowing over an arch. |

re mr2560: Yeah! Or put this on Wall Street and have it be a stock ticker...BTW, this is all the result of a similar posting, "H2O'clock" elsewhere in the bakery... |

Or maybe instead of the height of the fountain indicating pixel brightness, air can be injected into the water stream on an individual 'pixel' basis. Black pixels would run as air-free jets. The response time could be very quick, and the combination of side lighting and a dark pool bottom could give good visibility. |
