As a result of the collaboration between a German tech startup - MagnWall and top tier German retailer Breuninger, 3 window displays were technologically advanced at the main Breuninger´s quartier in Stuttgart. MAGNWALL technology of cable-free electrification in interiors was applied to the ceilings and back walls of the shop windows. Covered with exchangeable print graphics and powered through one socket - MAGNWALL panels serve as a canvas for placement of various visual merchandising and so-called mobile lights. Those have 2 major differences to old-school alternatives, they are magnetic and have no cables. Thus, in a plug and play manner, the window displays can be redesigned within minutes instead of hours. There are no cables or power lines visible, as well as no need to call for a handworker.
