Five nested scales of systems workExplore from Ecosystem on the outside to Touchpoint at the center. Hover, tap, or tab to a ring to reveal its scene.The city: zoning, codes, the grid, insurers. The rules every house lives within.The utilities and the people who keep the house running.Searching, buying, moving in. A life in the house over time.The house itself: its structure and layout.One moment of contact: a switch, a faucet, a door.
My work covers systems at every scale
