Here is an illustration for a possible indoor version :

Experimented eyes will recognize the Ikea table I stole from a PDF manual...
I definitevely have to learn how to use better tools that can do 3D ;-)

Basically the indoor version could be a scaled down version of the original, but with a handset, so that the sound would not be to disturbing for those who don't communicate.

I think it is important for this object to cohabitate with other activities taking place in the room, as it is supposed to be located in places that already have a purpose.

There can be several versions, some with wifi, some with 4G or lan, some with batteries and some which are plugged on the wall.

I have plans for a more complex indoor version, but I need to learn how to use CAD or 3D modeling tools first to be able to properly illustrate it.
