"Break out of the box

Traditional "grid of faces" teleconferencing is designed for presentations, not conversations. The presentation and audio processing prioritize one speaker over all others. All participant voices sound like they are coming from the same, disembodied location. Everyone is lined up in a rigid grid, like you're facing down a tribunal interrogation. "
