Check this out: Tholos.
Placed in numerous cities around the world, it projects the view from those cities onto the local screens and then likewise sends your images to the other Tholos centers around the globe… It’s like a video/audio portal.
“THOLOS thereby transmits life-sized images and clear sound around the globe. It produces a panoramic, 360 degree picture and enables audiovisual communication and real time face to face interaction.”
I’m impressed.
Its like a halfassed stargate type thing… if you could only walk through it and go somewhere else… that would be intense.
