It’s a spherical video in a triplified space with symmetry in space-time

MetaFilter favorite Vi Hart and mathematician Henry Segerman collaborated on creating Peace for Triple Piano, a 360° video with 3D audio in which Vi is singing “Dona nobis pacem” as a canon and accompanying herself on the piano while Henry is playing the triangle. But they added some space-time twists to the video, which they explain in The Making of "Peace for Triple Piano”.

The “Making Of” video is truly awesome. A practical application of conceptualizing four-dimensional space-time! Time crystals and sphubes!

I may be dense (and by "may be" I mean "am") -- it took until the third viewing for me to realize I could drag the cursor to pan around inside That Wonder. Was great before I realized that, then... Jebus O'Donohue!

If you view this in fullscreen in the YouTube app on a phone, you can "look around" by moving the entire phone, physically. Or if you have a VR headset with YouTube 360° support then you can really get the full effect, including the 3D audio.

This is gorgeous. Vi is a treasure.

And I am in no way smart enough to understand the making of video.

mbrubeck, I had only looked at it on my laptop. I didn't think it was possible, but watching it on a phone and moving it around makes it even more cooler. Mind blown!
