The original video: kzfaq.info/get/bejne/fsmCipZ3stvYpI0.html

Seeing the projections from rectangle to sphere then to planar view and then tripled absolutely blew my mind. Thank you for including an animation of it and not just showing the end product. This is absolutely astounding.

Figure out where your eyes are when you're sitting, then when you're standing next to the piano, and do some math to draw a line between your eyes that connects to the wall. Put a mark on the wall where the line meets it, and that's where you look when you're sitting. Same for a mark somewhere on the floor. I could be missing something when it comes to the curve of your eye line due to the sphere, but that's the solution I thought of. This video is absolutely beautiful. I always expect the best from ViHart, but this is just above and beyond. The making of really shows her attention to detail and her commitment to each project. The damper pedal got me, I don't think the average person would have noticed or cared, but she actually worked to fix even the tiniest problem.

I like this "unwrapped" version more because I can see all of it.

I thought it was absolutely amazing how the sheet music kept moving between the different clones and that a Henry could pass an object from one vi to another. I'm amazed at all of this and this is a reason why I love maths and music.

I knew after watching the original video that some funky stuff was going on. However, I didn't realise the extent of that until this one explained it all. Amazing work!

We shall call this visual feat "Shepard's Time" instead of "Shepard's Tone" ;)

Sometimes I come back to this just to feel the mindbendieness of it xD

When i saw the piano video my brain went WFT, and i thought "How did they do that?! How many pianos is there? Are they triplets? It must be some really advanced 360-filming and cloning going on, but is that even possible?" I didnt fully understand the explaination, but anyway it made me amazed.

Fascinating! And I learned a new term: "time sphube". Thanks!

This might be the single best music video. Insane that you worked everything out so beautifully. I didn't understand basically anything, but still amazing to see the final product

THIS IS AMAZING. You guys rock.

As a physicist studying manifolds in general relativity I adore how You nerd out in this explanation video with all the math details!

Favorite set of videos I've seen all year. So cool!!! Thanks for including the "unwrapped" version of the song at the end of this making of video.

This completes the performance so well.

....still witchcraft. o_O

This is actually the most amazing thing I have ever seen. You guys are awesome! P.S. Vi Gamma > All other Vis

I want a sphube for my birthday and also a triplysphere.

it hurts my brain but in a good way. that's the most amazing thing i've seen in a very long time

The way you plotted everyone's course by threads in the spiral was awesome!

Once again I am amazed by all the thought and effort that goes into (nearly) every video.

And I thought that my Buchla tutorials were a labor of love ;-) Seriously, Google needs to do a Doodle next Feb 26th to honor the day you guys won the Internet. Fantastic work!

I've been a fan of Vi's doodle series, but this just takes it to a whole freekin' different level. Genius!

Just simply amazing. Brought joy. :')

Really Beautiful, and this version has the pianos separated at just the right distance (in full screen on my computer screen) to overlap in my double vision, making a stable pattern in an otherwise unstable visual world. Hard to describe, you can just take - thanks it suits me if you wish...

This absolutely blew me away. This kind of stuff that at first is so hard to wrap your mind around becomes so much easier once you and Vi explain it, and watching the unwrapped video at the end is so satisfying to see how perfectly choreographed this is. I also like how you can just follow the sheet music around the video to see where set A is the whole time. Very very VERY impressive. I expect nothing less from ViHart, and I'm glad this collab worked out so beautifully.

At first I thougt it was a pretty normal video but after this video I'm absolutly baffled about the maths and all of your struggles

I didn't pay much attention to the original video since I'm generally not a fan of spherical videos, but I'm now going to figure out how to watch it properly since I now understand what it is. The two of you (that's you and Vi, not both copies of Henry in the video) really made something incredible here!

It's interesting to imagine the things and people interacting with one another in this space can actually belong to different moments from the same, single timeline.

Audio-visual spherical canon with a hint of space-time paradox. BEAUTIFUL! Or, as captain Janeway (ST Voyager) would say: "The best way to deal with temporal paradoxes is not to think about them." and "(...) the future is the past, the past is the future, it all gives me a headache."

I knew I was going to love the chance to see how the original video was made if I got it... and man, this was brilliant. Love seeing the maths behind it as well as the cool video tricks to make it all work.

This. Is. Insane. Mind blown.

I'm not as good at math as I used to be, but I simply loved this. When I was still good at math I would do calculus and trig at the same time without writing anything down and without calculators. Always arrived at the correct answer. Spent most of my youth doing math that way, always got the right answer after a couple seconds thinking about the problem. You can thank a bad teacher for that going away. Even so, I found this lesson absolutely enjoyable from the bottom of my heart to very depths of my brain. And even though I am multiple years late to seeing this video, I am grateful to have seen it and understood it at all. Well done!

If you right click the video, you can choose to repeat it so you could have made it infinite

*Mind blown*

This made it into my playlist of the ten worlds best videos. The intelligence of you guys obviously is totally off the scale 🤯👍

BLEW MY MIND OH MY GOD MATH IS AMAZING

This is got to be the most beautiful and profound thing i have ever experienced thank you

Once again, I am proved time and time again, that there are magical people in the world.

Impressive and beautiful! The best use of 360 video I have ever seen!

wonderful. from so many perspectives. thank you from my heart

Ohhh, now I get it! Except I don't.

what a great way to explain what time crystals are!

Pretty interesting, mathematically. Over all worth watching!

Came for an explanation, stayed for the sphube.

This might be the most clever video-puzzle I've ever seen. :-O

This is how I imagine time travel rules to be like, if it exists.

Beautiful! Just stunningly beautiful! Well done, you two.

god this is way cooler than I thought it was, you guys are absolutely amazing for making this easy to understand as well

I love it!!!! I love that in unravelling/explaining the finished video, you've created more art that is beautiful and interesting in its own right.

Also: I note that Henry and Vi's travel speeds through the video are in proportion to their speaking speeds. ;-)

This is so interesting, makes me want to experiment with this kind of stuff in the future. I am so glad I chose to watch this video as well.

Absolutely amazing!

This is so incredibly awesome!!!

O. M. G. ... Mind Blown! I loved this! The planning, the math, the explanations, the execution, the music, the singing! All of it! Just.. WOW! I'm glad I contribute, albeit modestly, to your Patreon. To help you to be able to do *THIS* kind of work!

One way to loop it forever would be to have the song end where it began, then put the video in a playlist. KZfaq would allow you to play the playlist on loop, and if the triple piano video is the only video, it'll play forever, even if the playlist is only two videos long.

There are some things in the universe which are so beautiful I will never understand them. This is one of them.

Wow, amazing!! Very inspiring, thank you so much.

The explanation is what makes the music and the video amazing.

I watched the original several times trying to figure it out before moving to this video. I would have never appreciated how amazing this is without that last flat version. Great work !

I remember the amazement I felt watching your doodle videos. I feel the same amazement again, only it's something absolutely new, and therefore even more amazing.

Such a beautiful accomplishment

I am utterly amazed! This is so lovely and cool!

This is so beautiful. The maths are so delightful. Thank you.

okay so this is incredible and makes me appreciate the math that can be done with spherical cameras so much more

This is actually the best video I’ve ever seen on the internet ever!

The spiral through spacetime reminds me of the cosmological paradigm of the Mayan calendar.

Outstanding!

Great video breakdown that shows how important math and science are to art :) the song and visuals are wonderful, thank you

Spectacular.

What a great job... impressive, bravo.

Just found this. I'm struck by some elemental things, mainly eyes and ears. Our senses are how we know the world beyond our skin, and how we express the world inside us - ideas, emotions et. al. Geometry is a mental construct expressing the structures observed and conjectured. What this means for me and this video is, the constant searching to "make sense" visually and aurally of what I'm experiencing. The repetition in the space-time was so difficult to unwrap that I just had to "float" on the experience in much the same way one does with optical illusions and aural counterparts. Not having a deep mathematical background and being an artist-musician, I really appreciated the explanations and videos of the process. In the end though, all we have as audience are our eyes, ears, and sensory experiences held in our brains. This is what makes abstraction so much fun and so incomprehensible all at once.

I'm really impressed that you can keep the time the whole way through

Wow. Just Wow. I am absolutely blown away

this is pretty fascinating. Oddly, i happen to be writing a trumpet-and-interactive-electronics piece of music around the subject of Minkowski and spacetime. I wish you had discovered this some months ago, it would have been a useful inspiration to the material that i've now (mostly) already built. amazing work, as always. Tau day forever.

lmfao i basically understood like 20% of the video, hella impressive shit this is next level

This, was beautiful.

this is amazing, hope spherical video picks up with stuff like this

spectacular idea. wonderfull video. please do this again with different kinds of music. bravo! pura vida.

I find the beauty of the video much more apparent in the flat version at the end of this video than the spherical original. Both great!

I sort of started to understand the concept xD This looks so complex and hard to achieve that I feel the need to congratulate you (it also sounds really nice). My congratulations will probably mean a lot more when I understad what's going on xD

Amazing! And I've spent all my available neurons for the weekend...

This is really amazing

I totally understood EVERYTHING you explained there! You guys are AWESOME! totally understood EVERYTHING you explained there! You guys are AWESOME! I understood EVERYTHING you explained there!

Gotta watch it back a couple of times, but it stills a freaking amazing job.

AMAZING!!!

wow it was awesome, and the math indeed really cool!

Why would you do this to me on a Monday? In all seriousness, this was incredibly cool and beautiful and only somewhat confusing. Great job!

Hofstadter would be proud!!

Stunned

That is just. so. wow!

Fantastic

I too have the theta V… but I would not have come up with this idea! Great job. Truly a great way of using the technology.

Amazing 👏

That's so awesome!

This is just so wonderful :0

Even though its nerdy and confusing to me, This is soooo AWESOME !!

Amazing.

really interesting video, i'll watch it again when my mind stop hurting :D

Woow! Really cool,video!!

You're a Time Lord, Vi Hart...
