I’m quite impressed with what they’ve accomplished here. Jessica is in Chicago and Wolf is in New York. The image was a little herky-jerky (that’s a lot of data to transmit) from multiple cameras that were surrounding Jessica in a small tent.
I don’t know for sure if the image was actually projected onto the set or just merged digitally, but Wolf gave the impression that he was looking right at the image. And there was a red circle on the floor that appeared as if it could have been part of the projection aparatus.
