I love these paper posters because of the use of colour and angles. The paper adds layers and a small effect because of the way you can see the paper is laid over one another. I think the different colour papers work well and could work for a key code.
Geometric shapes folded to make a geometric structure. This creates an interesting structure which could be very versatile. I see this structure as being a crazy shelving unit within an interior to shelf small products for the customer to view.
