The Paris-based design collaborative Radi Designers created the Icosahedron — which is a 20-sided shape — apparently as some kind of interactive experience for a cat. Made from folded cardboard, the Icosahedron has holes of various sizes cut in some of its sides. It appears that if a cat goes inside, the form would move quite easily as the cat peeks out the holes. I imagine that this might be extremely entertaining or somewhat annoying for both cat and owner. Would you condier this to be a practical piece of cat furniture, or rather some kind of interactive art piece?
