Check out my newest video 6 Amazing Magnet Gadgets! kzfaq.info/get/bejne/Zst8Z5VyrNKWmJ8.html

We have this in our 4 class as a book for fun. 😂

An Uncle came to our school and he gave this type books to us in childhood. I still have it. It works

The calculations for the angles in these must be incredible.

I remember that when i am in 2nd standered a magacian came to my school and at the end of that show he sells these Book for 5 rupee and i brought one 😢good old days 🙂

I have no words to say how awesome this is

this is a proof if concept for printing gifs!!!!!!

i remember we used to have a book full of these and they were collectible so u would get the images at the back and u had the paper so u could see them lol

1:20 I could hear that. 🤣

For those wanting to know how to do it, it's fairly simple. First decide how many frames your animation will have (for a 4 frame animation, make the bars on the acetate 3 blocks thick, with a 1 block space between each) Then create the images for your animation. Use your acetate image as a mask on each frame of the animation (offsetting it by 1 block for each frame)

There are two people: The old, who was here 5 years ago And the new, coming due to the strange recommendation.

I remember that in Peru we had years ago, a History album that used this to make their stickers move. Incredible!!

This is really calming!

KZfaq: let's recommend it after 10 years. Le me :internet existed back then

This is creepily interesting

You dont want to search but got this in recommandation 😁 Joke aside Bachpan yaad a gya😍

Who else got this video in reccomend after 10 years

Ya, I remember that I had a playing book with these sketches and this horizontally lined plastic sheet. Childhood memories got refreshed. Its literally amazing! 😘😍

Those were some brilliant optical illusions Brusspup!🎠☺

Finally found that so called magician who sold me this when I was 8 years old 🤣

Every year 1 magician comes in my school to show this book and I purchase it😂😂

Nicely done. For the waves, you see the "beat" (difference) frequency. Frequency is 1/period. So the length of a cycle of the "animated" pattern is 1/ the difference of the two other pattern spacings (periods). The motion demonstrates that phase difference is preserved (coherent) in the process. This is how a part of most radio and TV receivers work. Example with easy to see numbers: Spacing #1 = 4/16 = 1/4 (Freq = 4) inverse = 4/1 Spacing #2 = 5/16 (Freq = 3.2) inverse = 16/5 Freq difference = 0.8 Inverse of 0.8 = 1.25 = 20 /16ths 20 /16ths is longer than either of the two periods. The difference frequenci is smaller (lower) that the other two and therefore easier to amplify (in a radio). Make the wiggly lines different periods and the waves will have different frequencies. This is called "mixing", or heterodyning in radio. Thank Maj Armstrong.

I have got to get a hold of that.

This is called sub-sampling. Having fewer samples than neccessary of an image makes things that supposedly weren't there appear

Some years ago I bought this for fun😍

A lot of people have been wondering how this thing works so I'll tell you. That plastic thing with the black lines on it only exposes that little bit of area where the black isn't. So when it passes over the paper which has the ''code'' for animation, it shows only some of the picture. So in more simple terms, All of the weird lines on the paper match a certain different line somewhere else on the paper therefor making them visible at the same time through the plastic thing. As the plastic thing moves, different lines come into view and cause a movement kind of thing. The ''code'' looks like stairs meaning that the animation has movement like going up and down. This was a pretty bad explanation but I hope this helped. :D

I had a book of these when I was younger and they still impress me

I had this when I was a kid. We used to play and we used to get fun when the image was moving.

*It’s amazing that the amount of news that happens in the world each day fit exactly the length of newspaper* 📰

SUCH ELEGANT ANIMATED OPTICAL ILLUSIONS!

What I would like to know is how do you come up with the design that reacts in such a way to a visual obstruction such as the sheet of black bars? This makes me think you can do more than just black bars, but other shapes as well if you can get the pattern right.

How do I make these!

1:13 wakka wakka wakka

Last one was just superb.

When you look at the stripes for a while and look away, it’s like those videos with the illusion swirling!

Don't stare at the line for the whole video it makes your eyes go crazy af

Can i have a paper like that?

This is amazing! Out of the world!

Where do you get that black and white stripes page? I have a book that has drawings like that but can’t find the paper thing he uses. Where can I find it or what is it called?

I WANT TO CRYYYYYYYY THIS IS BEAUTIFUL :")❤️

Your work is just amazing! My mind is blown.

We had these things as kids. So much nostalgia

Loved your illusions and music.

was that drakes head

who else loved these books when they were younger

I think optical illusions should be a specialisation within any academic arts program, given the complexity, similar to how maths is used to generate art, it often overlaps w science and engineering. Serious exhibits of these would be so neat.

10 million views and 10 years is the greatest optical illusion of them all!

OMG HOW R U DOING THIS? THIS IS SSOO AMAZING!

This is truly amazing :D and i really love the piano music :D btw the song is called Moonrise by Brusspup

Love this! Can you do it with an image that has details, not only silhouettes?

Totally amazing! Thanks for sharing. How about another video showing how you figure it out? 👏👍

amazing :) from phillipines

WHERE CAN I GET THE PAPER WITH THE DRAWINGS AND THE OTHER THING YOU MOVED OVER IT!!!

Ohh My God!!😯😯😯Really Amazing!!!❤️❤️❤️

I'm seeing a lot of moire patterns after watching this playlist. lol. Nicely done.

Anyone has the link to those pics?

Do you still have the images from this video so we can download them like you posted in your others?

It is called scanimations, and Rufus Butler Seder created these type of illusions and its really cool :)

What kind of black magic is this?

2017

Can you explain how to do that with photoshop (with your 5 pictures) thanks

please someone tell me what is this animation called...ASAP NEED IT FOR COLLEGE WORK. THANKS

Recommendation brougt us together again

I have a book of these and it cost only just 0.25$

Hi! I´m doing a physics project about sound and light and I wanna use this video for an example so can you or someone else explain me how I can write about it

How it's made? What's that black colours up? Paper list trasnparent?

OWWWW. My braiiinn. Oww, Doctor, I need a new one.

I used to do stuff like this.........until I took an arrow to the knee

That is very clever and looks amazing!

this is the best art ever.

What the hell !!!!

It looks fantastic, but I think it's kinda weird 1. the second person must have had a broken neck since his whole head is able to be turned 360 degrees, especially it's more than just turning "once" 2. has anyone been running "backwards?" 3. I don't think the Parkman is able to finish eating and spit it out... ewwwwww

where do u get that line label sheet from?

Crazy! Never seen anything like this...

what paper do you use ?? that black and white thing??

This is the best thing I ever seen

I’m trying to use this Oman design for a glass art installation. Are there any tutorials on how this works?

The fact that he/she drew it him/her self is amazing!

I wonder where you got it or how you made those black lines, can you tell me?

is there any available file to print that optical illusion? id like to have it.

This gives me nostalgia

Man,this thecnique is so old but still legendary,only a few people know it.

Where did you get the black and white paper?

I appriciate this kind of technology i can say it is an ordinary created animation ever

The pac-man one was my favorite! That's so cool!

Where do you get that board

what is this method of illusion or animation called?

This one is such a crazy skill !

Oohhh memories!!I had the same thing.........when I was in 3rd stand

What do you done to my eye background view!

You get all the frames for your animation and split them apart into many columns of pixels for each one. Then you combine them all together. To do this, first place down the first column of every frame in the order you want them to appear. Then repeat until all the columns have been placed down. Then you get a piece of transparent plastic and print black stripes. The width would number of frames you have - 1. This way, the sheet blocks out the other fames and only show one. Now move it and look!

Can somebody tell me what kind of illusion is thiss? What's the name of it

This is pretty cool!

Simple & amazing...!!!

What the heck?? How does that work so cool!!!

How is that even possible or how does this work? Is there a separate video for this? I wanna knos

Where do we get that sheet? And wt is it called?

where can you get/download the things??

muy chevere tu video , me gusto que ilucion optica como que engaña la vista con ese reflejo , en verdad me gusto.. ojala tenga mas como este para seguir mirando..
