In honor of nothing in particular, the tic tac toe fountain is probably best placed in a children's zoo area. I guess you would have the X controls on one side and the O controls on the other, or next to each other on the rim. A more advanced version would play Go and a more ornate version would use a great many jets to play chess. In fact, you could treat individual jets as pixels if there were enough of them...Guess you could play just about anything that way.-- cloudface, Oct 07 2003 Pixelfountain http://www.halfbake.../idea/TV_20FountainTelevision display as fountain or vice-versa [cloudface, Oct 17 2004] The "controls" can be grids of water jets. Cover a jet, and back-pressure places your X or O.-- Amos Kito, Oct 07 2003 Interactive squirt gun fountains... hmmmm-- RayfordSteele, Oct 09 2003 random, halfbakery
