Can you tell what it is yet? The return of the 'magic eye' picture - only this time it's a VIDEO
- Young Rivals video uses the magic eye phenomenon to 'hide' its music video
- Users must defocus their eyes to see it
They were a huge hit in the 1990s and now the Magic Eye is back.
The dot-filled patterns, which look like static on a TV, reveal a 3D picture if the viewer defocusues their eyes.
Now Canadian band Young Rival has resurrected the idea for its latest music video.

Can you see it? The latest Young Rival video uses the 'magic eye' phenomenon that requires viewers to defocus their eyes
HOW DOES IT WORK?
A stereogram is an image which, when viewed with two eyes, produces the illusion of depth perception.
They were made popular by the Magic Eye book series in the 1990s.
These versions were made on computers, and use subtle changes in a repeating pattern to combine depth information for both eyes into one single image.
By tricking your eyes into viewing these images a certain way, a three dimensional scene is visible.
The video shows the band in 3D, along with shots of TVs and other items.

To view autostereograms, the viewers has to 'decouple' or defocus their eyes, tricking the brain into seeing the slight variations in the repeating pattern as depth information.
'They're cool,' says the band.

'Some of you will already be familiar with the autostereogram, which was popularized by the Magic Eye book series in the 1990s.
'They are made on computers, and use subtle changes in a repeating pattern to combine depth information for both eyes into one single image.
'By tricking your eyes into viewing these images a certain way (see below) one can see a three dimensional scene.
The band say the key to seeing their video is to defocus your eyes

The band also created different versions of the video, a cross-eyed version, a parallel-eyed version of a version showing the 3D information, allowing users to experience the video even if they can't get the effect to work.
HOW THEY MADE IT
'We collected real-time depth data of Young Rival performing the song using an X-Box Kinect hooked up to a computer.
'The computer was running software called RGBD toolkit, designed for capturing the depth information from the Kinect using its built-in infrared system.
'Once we had our depth information, we unpacked it into image sequences and edited these sequences as if they were regular video.
'The only difference in the editing process was that depth was represented by luminosity.
'With much trial and error, we then ran the data through an algorithm which took each frame of depth information, converted it into a random dot stereogram image, and repacked it into the final video.
'Lastly, there was one more colour pass at the end, and voila.'
