If this technology advances and matures, then we might have a novel way of displaying paper artworks and textiles which are held onto a metallic wall by way of a single sheet of clear magnetised plastic - something akin to just having a piece of Perspex in front of the artefact without any frames or hanging implements. What's more interesting is that strength of the plastic magnet can be made to measure!
