Like everything else on a computer, the digital image exists as a double: • surface

(visible for humans) & • subface

(computable by software)

Multimedia for All!

The static image is not at the height of the medium algorithmic art. In any case, the image must be in motion: whether it is a dynamic installation or an interaction with the environment, that does not matter. (Nake, 2013)

Multimedia for All! From static images to interactive installations!
