This model works with the sharing concept of bundling. The pencil modules are bundled together and staggered at different heights to create spaces of seclusion and spaces of interaction/observation.
This model works with the concept of intersection. The four clothespins are separated slightly to create spaces for intimate gathering within each clothespin, and a central space of public gathering where the four pins come together. This intersection of paths works to create a shared space.
These three cups, while creating boundaries between one another, use the angled geometry of the cup to create a focal point. All three units share the same focal point, thereby creating a shared experience by framing similar views.
