An Audioquatroscopy is a new type of moving graphic design, whose rhythm is linked to a well-known classical music piece. A quatroscope is a four-sided mirror tunnel, similar to a kaleidoscope, but built of four, rather than three mirrors. A square image placed at one end - when observed from the other end of the tunnel - is reflected repeatedly in four directions, leading to unexpected and fascinating patterns, which change, when the central image is moved.

Audioquatroscopies are videos in which quadratic images of interesting objects are mirrored repeatedly and moved to the rhythms of well-known pieces of the classical music repertoire. They thus synthesize  optical with accustical signals to a new and gratifying experience.

The audioquatroscopy, that best illustrates some basics about the optical behaviour of a single square image is: Gershwin and Love.

An optical peculiarity is: When a square is rotated, empty spaces at the corners emerge. In my quatroscopies these spaces are filled by mirroring the image along the boundaries of the square. 

Audioquatroscopies can be produced with any number of classical music pieces and a large selection of images. Below I provide a list of my production so far, grouped into image themes (i.e. paintings, nature, landmarks and human artefacts). All can be examined on:

How I got to producing audioquatroscopies
Audioquatroscopy evolved from my previous work on quatroscopes. In a quatroscopy a single square image is repeatedly reflected  in four directions, leading to a mosaic-like pattern. In reality, a quatroscope is a long mirror tunnel, consisting of four rather then three elongated mirrors, such as in most traditional kaleidoscopes. My first quatroscopies were produced in 2014 using a 5x5 cm square, 33 cm long mirror tunnel, placed in front of a computer-screen. Images were moved on that screen until an aesthetically pleasing pattern emerged, that could be recorded with a camera. 
The quality of the pictures taken with a camera was, however rather poor. Consequently quatroscopies were produced digitally from input images using Photoshop, such as this quatroscopy of Niki de Saint Phalle's Nana:
From 2017 to 2022 I have produced many digital quatroscopies with square images of many themes, which were mounted on a thin aluminum board and shown at several exhibitions. Some quatroscopic patterns have been used on clothes, bags, shawls etc. (see
During the initial explorations with the camera, however, the observed pattern changes remained a fond memory until 2021. Then I found a computer specialist, who agreed to build an algorithm that would allow to build a quatroscopic matrix based on the input of a single square image, and then move the input image and to the rhythm of a musical tune and show the separate movements of the 49 squares as a video. I called these videos audioquatroscopies.
My vision for Audioquatroscopy could be realized thanks to Nik Hidber, Sandro Ducceschi, Apple, Google, and Adobe.
