The experimental film "Choros" directed by Michael Langan and Terah Maher modernizes the visual echo technique developed for scientific study in the 1880s.

In the late nineteenth century, a photographic technique called "chronophotography" began to develop, whereby multiple photographs would be taken in rapid succession to study the movement of a given subject.

Eadweard Muybridge famously filmed a horse in motion in 1878, providing the world with its first taste of motion pictures when the images were displayed on a spinning zoetrope.

Several years later, the French physicist Etienne-Jules Marey developed a stunning variation of this technique when he captured multiple poses of a subject over time onto a single frame of film, rendering a kind of visual echo.
