Approached by clothing designer Walter Van Beirendonck to design a shop concept for his W.&L.T. brand, Marc decided upon a modular display system, made up of easily portable pieces that could work as shops-in-shops, pop-up events and trade fair booths. Marc designed a series of coloured plastic display modules made from indestructible polypropylene that could be fit together in a variety of ways.  During opening hours, the pieces of the modular system were spread apart to display the contents; and during closing hours, the pieces could be rolled up against each other, creating a closed box to conceal the contents. Marc also designed rubber tiles with W.& L.T. branding that could be used in the retail concessions, and additional tables and chairs to match the display modules.
