Wiggle stereoscopy

Wiggle stereoscopy is a way to see 3D images without using special glasses. Imagine you have two eyes and each eye sees a slightly different image of the same thing. Your brain combines both of these images and creates a 3D experience for you.

Wiggle stereoscopy works in a similar way. You have two pictures of the same thing, but each picture is taken from a slightly different perspective. When you switch back and forth between these pictures very quickly, the images seem to overlap each other and create the illusion of depth. This is because your brain is interpreting the slight differences between the pictures as depth cues.

To get the best wiggle stereoscopy experience, sit close to your computer screen or hold a printout close to your face. Look at the pictures and start wiggling your head back and forth very quickly. Alternatively, some websites and apps may have a "wiggle" button that automatically switches between the two pictures. Keep wiggling until you see the 3D effect!
