Wait a minute...
I'm just noticing details that I haven't noticed during the video viewing at the event

There's a bunch of objects spawning that track perfectly for both translation and rotation on the hands, feet and other parts.
Does this mean the map itself attaches it to the dancers? That's pretty cool if so

Like pic related axes just spawned in time for the video. Best one was the gift boxes that just shows up out of nowhere too
