We test a working version of the full system - 6 unique monoliths with embedded computers, cameras and speakers, a central core of speakers, and a central control workstation in-house in Mother's basement. It isn't an ideal way to test - the sound reflects all over and is vastly different than what we will have on-site. But it gives us an idea what to expect, especially in terms of people's first-time interactions. Our take-away from this session is to make some changes to the musical arrangements to exaggerate interactions and make them more obvious.
