Rolling Ball Sculpture - created by David Morrell 

Great quirky haunting music. Thanks for including the link! I love kinetic sculpture and ball runs, the effort put in and resulting quality of this one are apparent.

Very pleasant to watch! I would have loved that, at 3:01, time enough was allowed to watch the full sequence, with the full sculpture in frame.

I LOVE the counter on this one. You are inspiring, Mr. Morrell!

Thanks Tom, It was initially going to be a 6 ball tipping arm, but it made the sculpture too busy all at once. I researched a heap of kinetic sculpture info and made something similar. I'm always thinking of new ways to make components, but remember, I do love that release mechanism of yours!

I wish I could like this twice! I have two thumbs in real life, and if I had two thumbs in RU-vid, they'd both be up right now.

You make 7 years ago a perfect video about that awesome track in a perfect quality😱 how!?

2020? Also kinda annoyed you didn’t show the full run but clips, still a cool intricate marble run

this tune made the most of my b&o laptop speakers!

Nice closeups on the balls, and interesting music 👍 And that part at 1:06 was really cool; I'm not sure I've seen something like that before!

David morrell sir rolling Ball sculptures are cool and excited for example their bunch of rolling Ball sculptures.

this is true Art & engineering - thank you for sharing

Hypnotic, there something almost magical about these.

Pretty good youtube reccomendation for these months of quarantine.

There is something about this video that, for me, seems to make it particularly compelling. I think, apart from the sculpture itself, that the music is particularly well suited to it. I even like the music for its own sake. I've pulled this up several times just to run it while I'm doing other things on the computer.

I visited a science center and there was one of these thingies and there were parts where the marble fell about a rulers length, bounced on a block of wood, and landed perfectly on the track and carried on rolling.

This is the coolest thing ever!!!

My cat would be absolutely riveted.

Thanks, Dave. I don't feel I can take much credit for that release mechanism. I just looked at Matt Gaulden's release and was wanting one that was a bit simpler and quicker to make. Soon I will have something big to show off. I worked on it for over two hours tonight, and I think I only lost one marble during testing. Getting close!

YESSSSS! I LOVE that multi-track switch!!!! I was just thinking of how to design one this past week! You've beat me to it again, Dave. One of these days I hope to have enough time to develop and implement all the things in my head so I'm not feeling like I'm following in your footsteps every time I do something. Nice work!!! I am envious. Oh, and cool music too!

Super mesmerizing to watch.

It is a cool piece of music, for sure! Glad you like it.

Wow, amazing! And here I was all proud of my little copper one. :P I can't imagine working all of those out of steel. It must be hard to sell them once you're finished... The music is perfect for this, too.

This is beautiful!

It seems I'm at the early tide of random recommendations

Beautifully shot video. Nice sculpture too. Those fake sections are great looking.

This video plays like it should. Awesome!

+1 with regards to the track switch. And of course the rest of the machine is fabulous as well.

Cool video, very nice editing! And a great sculpture, obviously :)

This thing is beautiful.

I love these rolling ball sculptures, but it would have been a better video if you included the entire thing, so we could see the full marble run at least once.

Woww... Spettacolare... Stupendo... Complimenti

Wow 25mm marbles that track must be alot bigger than expected

Thanks!

55 ppl who suffer from sfairesphobia, pour things. Amazing work btw!

I like this😍

I can't believe you used part of a mac to make this.

Interested in purchasing: 1) an RBS with a Bing-Bang-Boing sequence - using small drums with rubber heads.which the balls bounce off of and then land in a cone collector 2) an RBS with Evel Knievel jumps where the Balls fly off a Ramp . . sail 1 to 3 feet through the air . . and land on a receiving Ramp Sadly - no one has ever put these rather simple ideas into an RBS

I love it! 👍😊

3:03 *SWITCH* 3:03 (Thanos snap finger) Pull focus eye back, and see it!

I love the music

This is amazing!

saludos, hermoso diseño y gran trabajo!! 👍👍👍👍👍, saludos desde el estado de México.

amazing

Perfeito parabéns 🇧🇷

Cool i want one!

Браво!!!

The music sounds like someone's on a typewriter. I like it.

Do u solder or weld them together the joints and rails etc.? I’m thinking of building one myself is why I ask even since I seen one of these a long time ago I’ve always wanted to build one just to play with any tips would be helpful like what kind of materials best cheapest metal to use to rails etc. not looking for anything extravagant just want it for my workshop thought it would be a fun project for me and my daughter

Sort of reminds me of those old pinball machines.

いいですね、BGMもぴったり。

Everyone's different... but I would of liked a wide shot for 5 minutes n no music. I'd prefer to hear the marbles on the run, especially if you're selling them.

This is mesmerizing :0

This is so cool

back in my day we used to call those marble runs or marble tracks but ok

why does this marble track remind me of willy wonkas bonbon fabric?

Very nice. Exelente.

2021

needed a shot of the whole thing running for like a solid 20 seconds at the end not just like 5 seconds man.. i was waiting for the shot the whole video and then it only shows it for like 5 seconds??

yeah i gotta agree with these guys come on, wide shot. even for 7 years ago this isnt ok, unless ur at least 60 then ill give u a pass this time.

This man has written اللہ (GOD) unintentionally in his work at 1:33 No doubt HE is every where.

WOW!!

Now imagine if this was a roller coaster ride

Hey David, I was wondering whether you soldered or welded this sculpture. Thank you in advance :)

I think this can be considered a perpetual motion machine.

beautiful!!

Road:wow Ball:wow

Nice

Video doesn't play Without skipping.

먹을만하네요

Amazing

What do you use for bending the metal and is it welded or soldered?

mables very busy

Keren..

Hi and thank you for the great work, I have a Q please, you know I got a lot of clothes hanger can I use it for the making ???

there's one just like this in the science center in california

Very cool. Just curious - the loading mechanism is obviously motor-driven - but is it even possible to design a 100% perpetual / kinetic sculpture? Has anyone ever seen one...?

Hi, awesome work!! What gauge wire do you use? it looks pretty big, 10-12 gauge? thanks

Really awesome! Can I ask what method of soldering you used? Eg, flame, iron, resistance etc?

Even cooler if the marble lifter is powered by perpendicular energy like water or wheels. Doesnt mean this is not a cool sculpture thou. I just give an idea to improve.

Amazing...

Where is discription

Really cool but a wide shot would have been great. And that music... had to turn down the volume. Ugh. How about the sounds of the machine?

Alguno sabe un vídeo de rock suave en inglés donde sale unos jóvenes tocando en un apartamento y a su alrededor sale este juego de esfera

めっちゃすげえ

Excelente ✌️ Bom trabalho amigo 👍

muy interesante el juego

Great 👍😊

hi David. what do you think about bronze to make the track?

can you make a one hour video of only the final perspective? =) =)

*Fun Fact: You did not look this up*

WOW!

Wow ♥️👍

amazinggg

الله the cover of the video looks like

Can you make a mechanical binary counter using that?

Yuppppp 2020 and we`re back again LUL

What kind of balls did you use?

I wish my father can be this good lol :>

Hundredth!!!

I would like to build something like that. Can you give me some details?
