For my PhD research, I've been bouncing ideas around for how to volumetrically capture a performance or classroom session in 3D, and then layer on additional contextual data (interactions between participants, connections, info from dramaturgy, info from SoTL, etc.).
This NEBULA experimental jazz video by Marcin Nowrotek kind of gets at some of what's in my head. Imagine this, showing a group of students collaborating in an active learning session, and instead of notes/percussion visualizations, some kind of representation of how they are interacting etc… Also, since it's all in 3D, imagine being able to interact with the recording in 3D using fancy goggles.
Thanks to BoingBoing for the link!
