Design pyramid and tetrahedron business cards (2015-present): original work here, newer models below. Made with a mix of Rhino 3D, SketchUp, Adobe Illustrator and Affinity Photo, and magnets and paper and glue. I have been using this pyramid to explore and better understand the relationship between the facets of my work - design, technology, business, and people. The shape of the tetrahedron is perfect for describing the relationship: there are four faces, and each face is always connected to the other three; what matters is not any of the individual faces, but the shape they create when they are leveraged together.
