MN is a symbol of National Museum in Warsaw. We got inpired by the color and shape of the visual indentyfication of this institution. We designed the stand in way, that the user looking down from the entresol could see the logo of National Museum and while beeing at the bookstore level he will see the cascading shelves. Our project is simply a „zigzak” on the basis of which we created bookstore shelves. The customer passing through the installations has the possibility to interact with the installation and look at it from many different perspective.
