would be nice to stream this to a screen on the wall in my home office

I once toured an elementary school in one country that was "twinned" with another elementary school in another country.

One of the classrooms (4th grade, maybe?) had one wall that was entirely a projection from a camera set up in a classroom of the other school. The other school had the opposite setup.

The effect was of one large classroom, though the projected one was naturally a little dimmer, fuzzier, and de-saturated. But I was told that even though there was no audio link between them, the children of the different classrooms got to know each other on sight, and formed social bonds.
