"Now we consider a rotating frame of reference."

The end was like when the bad guy in anime says, “that wasn’t even my true form”

no GBC creator even comes close to the ingeniousness that is Akiyuki

This is the best one yet.

I already thought it was so mesmerizing to watch at the first part. Then, filming from different angles and making the entire contraption rotate, I almost lost is. Amazing!

Beautiful!

The whole world : Keep It Simple. Akiyuki : Hold my Sake.

From a mechanical engineer to another: this is incredible! Excellent work! And ingenious ideas! I cannot imagine how many hours it took to design the stationary core with the rotating base. It looks fantastic. Congrats!

I like how you showed the individual components while slowly putting the whole contraption together. It certainly improves the video experience!

The master is back! Excellent module!

“Any sufficiently advanced technology is indistinguishable from magic.” Arthur C. Clarke Dude you’re simply a wizard at this point xD Amazing work as always !

It’s always so hypnotizing when the whole contraption rotates and it appears the rings are stationary, yet they’re changing angles! Well done!

Absolute genius. Watch to the end!

You sir have outdone yourself.

6:05 I actually shouted out "No way!" Mindblowing work!!

Absolutely amazing LEGO engineering. It's really a masterpiece!

Always taking it to the next level! I love the rotational view to really show how the levels interact! Very well built and demonstrated!

Wow, this is just a brilliant construction! So much creativity and technical skill in this build.

once again, akiyuki proves his absolute dominance of the art form

This video was so well edited. It was awesome seeing the progression of ideas advance and improve.

things like this would go so well in an art museum! imagine a room just full of contraptions like these and you can just watch them all day!

When you stated to play with the rotating platform I was really impressed ! Great job 👏

First upload in 6 months. Finally.🥳

Wow, every creation you make!!! Every one is my favorite. We learn so much from your ideas!!!

I already thought it was genius and then I got to 6 minutes 🤯 omfg

Just amazing! It was already great, then they add another component to counter the rotation which gives it a totally different effect. I agree with others, this is one of the most interesting GBCs yet.

For me, it's the sort of things that are normally useless, but are very interesting to watch, so it's concentrating you and it makes it useful...

The stationary rings version is awe inspiring. The movement of each arm is so elegant. Nice touch to highlight it in the video.

1 Ring: Oh that's cool, though a bit tame for an Akiyuki device. 2 Rings: Ahhhhh, there we go, that's more like it. 5 Rings: ALL HAIL THE INFINITY ENGINE.

The reverse spinning of the base was genius representation 🤣 Love it!

The most beautiful thing is: everything is so clean. Not even a stain. Look at that pure white background. It is like heaven.

Downright spectacular. The gears and framework needed to make all those rings spin at a tilt is amazing. Respect++

Amazing idea to stack the rings vertically.

W O A AA W !! ! ! ! I want a Real elevator that works like that, could be a flat ride for amusement park

Engineering at its finest! The movements are graceful and it looks beautiful!!

I'm a sucker for modular designs like this. Easy to maintain, easy to calibrate, easy to replace parts. Wonderful.

"This is cool, a tilted ring. Lets stack it on top of each other."

横から見た絵にすごい機能美を感じました。お見事！

Wow! Incredible design - and it all seems to work so flawlessly!

The pivotal moment in this video is from 1:13 - 1:33: adding and adjusting the second ring to the build - brilliantly done!

This can keep going right? How high can you get this before you start needing reduction gears and compensators?

I lost my mind when he showed the second contraption

This is the most satisfying Gbc module i ever seen! 😱INCREDIBLE!😱😍

Boy that marble machine XX is coming along splendidly.

I showed this to my friend and he was like "what's the point it just moves balls around" I nearly slapped him but then I remembered he's an English major and not an engineer, bless his little heart 😒

The glorious return

My mind was blown even further when the rotating base was added. Great work!

Absolute genius! No words to express how good this is.

Return of the King

"It is beautiful. i have been watching this for 5 hours now."

So cool!!! Seeing your gizmos make me feel like a kid again, in awe.

Amazing piece of work in terms of the visual aspect. Elegant.

You are genius, right?

Amazing, original, mesmerizing and just plain brilliant!

thats a beautiful amount of synchronization

I have seen quite a few of these gadgets, but this one is among the most aesthetically pleasing. Well done.

Oh My Goodness - This is so Amazing and Mesmerizing. Thank You for building and sharing.

This is amazing! What wonderful engineering. And the full rotation near the end!

the use of the torque transmitter to also serve as a phasing alignment tool is Pretty Cool.

Amazingly amazing. Just gets better and better as the video continues. Wow.

Just a brilliant piece of engineering and creativity. You can have form and function.

最後に当たり前の顔してボールベアリングじみた事しててすげぇとしかならなかった(語彙力)

In one word: mesmerizing.

Blown Away!!! Mesmerizing to say the least.

Exquisite mechanism. Bravo!

Wow, this is really great and impressive. Things just kept getting better.

Incredible work! I could watch this all day.

The beauty and perfection of movement that should be merchandised is amazing!

The spinning end section just blew my mind! Awesome!!

Wow this leaves me with no words to describe just how incredible this is!

simply fabulous! I could watch it all day.

That is marvelous! I am impressed with the rotating ball exchangers. That's a mechanical marvel.

Great engineering! Please make more like these. They're very inspiring .

You've got me hooked. It's mesmerizing. Thank you. ❤️

I love these lego balls contraptions they are so amazing, especially your contraptions

So nice mechanism and principle. Great job.

Just Amazing and beautiful! Congrats!! My fav ever!!

Thank is so cool! The top down view is so much fun to watch.

I don't know why exactly, but your lego mechanisms are always so satisfying to watch in action.

You blew my mind with the first concept,... Then shattered what was left of my mind with the 2nd concept.

This is one of the coolest things I've ever seen. Period!

So complex yet so smooth! Fantastically well done!

Ok, this was already incredibly impressive, but the spinning part is absolutely jay dropping and mesmerizing to watch!

I just love everything about this

Wow! That just looks so satisfying! That top angle looks so cool

Very nicely put together video and very entertaining as well. Thanks for posting this.

I was already impressed by the first layer. My mind couldn't process the rest.

Well, this is amazing for sure. One of your best creations in my opinion.

what an nice build ! ingenious AND artistic !

Turning the entire thing into its own turn-table absolutely blew my mind! Lol

This contraption is quite pleasing to watch.

This is the most satisfying video about lego engineering I've ever seen.

It's so sophisticated, it feels like a manifestation of madness - in the best possible way, of course.

The first iteration was epic! When you made the whole contraption rotate, you made it epicer! It also gave me motion sickness and I could only watch it for a little bit. Well done!!!

I love everything about this.

That's just brilliant, that is. And fascinating to look at!

The greatest minds and cleverest designs. The hardest effort and the end result is the ball ending up back where it started.

That someone could create this is baffling. Truly ingenious!

This is nothing short of amazing!! What I wouldn't give to have the plans and bricks to make this myself.
