To the permanent exhibition of Science Museum ‘Technorama’ in Winterthur, three new stunning installations by the Basel-based artists Drzach&Suchy have been added.

Shadow Casting Panels (SCP) is a novel technique for storing and presenting multiple images using one physical object, so that separate images become visible under varying illumination.


It was invented by Drzach in 2004 (patent pending), and then developed further by Drzach & Suchy. The further development of shadow casting panels led to shadow clouds, which are three-dimensional object, consisting of multiple shadow-casting elements semi-randomly arranged in three dimensions in such a way, that depending on the direction of illumination the overall shadow of the cloud displays various images encoded in it.
