Stereograms are 2D images that hide a 3D image inside. These images are created using a technique called stereopsis, which is the natural process by which our eyes perceive depth. Each eye sees the world from a slightly different angle, and our brain combines these two perspectives to create a three-dimensional image. Stereograms mimic this process, presenting a slightly different image to each eye.

The history of stereograms dates back to the early 19th century. Sir Charles Wheatstone, a British scientist, carried out pioneering research into binocular vision, which led to the development of stereopsis and eventually the creation of stereograms. However, it wasn't until the 20th century that stereograms became popular thanks to the work of Bela Julesz, a Hungarian scientist. Julesz created the first stereoscopic stereograms using computers, allowing previously unseen accuracy and visual quality.

Stereograms are a unique visual art form that challenges our perception and immerses us in a world of depth and dimension. Their rich history and ability to captivate people of all ages make them a timeless form of entertainment.

We invite you to challenge your senses so that the next time you find yourself in front of a stereogram, you will take a moment to look beyond the surface and discover the hidden world waiting to be revealed. In this way you will train your brain to interpret
