    I put 2 systems side by side to make a 30″ x 80″ box (with MW632ST projectors). It works pretty well but the virtual water doesn’t flow from one system to the other, of course. I use it as a flume tank, and use real water to demonstrate erosion of a stream bed.

    I don’t believe that model does 4:3, which I think is important to match the camera. Can anyone comment on that?

    You can see our flume with double (side-by-side) systems at http://zephyrmarine.org/2016/06/21/june-news/ It is located at Zephyr Education Foundation, Woods Hole, MA

    Yes, I have. I’ll try to post some photos on this. If it doesn’t work, email me at

    About 1 1/2 years ago I ran real water in a 40×30 box (clips on our website). Really cool because the camera sees through the water and you can see the bathymetry. The latest photos I have are of a dual system (80 inches long, but just dry). I am about to do some runs with real water again (in the 80 inch). I use a small boat bilge pump to cycle the water. If anyone wants to try it, you might contact me as I learned a few tricks.
    (The reason the match looks a little funny is that one projector is 3000 lumens, the other 3200. Got to fix that.)

    We don’t use the DVI. We use a hmdi splitter to split the signal, one going to the sandbox projector, the other to the classroom wall projector. They cost about $20, plus you need 2 more hdmi cables.

    Probably the (distance) threshold for ‘water’ is too close to the camera. If you go to “box layout”, the third number (and last number) of line one should be changed. In this case it should be increased to maybe, 100 (or 102 or so?). Experiment with this number, its the distance from the camera that it interprets as water (beyond this number), all above this would be land.
