One city. Four connected systems.An original black and white conceptual city cutaway traces four yellow networks. Electricity uses a solid line, water a double pipe, internet a dashed link, and urban rail sleeper marks. Numbered labels distinguish the systems. Choose a system below to highlight its route. This is not a map of a real city, and route animation is not a measured flow rate.EVERYDAY SYSTEMS / CUTAWAY 01CONCEPTUAL · NOT TO SCALE01ELECTRICITY02WATER03INTERNET04URBAN RAILUNDER THE SURFACEFOLLOW THE LINE.

CHANGE ONE THING

What happens
to everything else?

A pump stops. A network link fails. A train waits a little longer. Explore how systems respond with five transparent, simplified experiments. Pin a result, change the assumptions and compare.

NEW / THE CONNECTED CITY

Four systems.
One shared story.

A commute, a power interruption, heavy rain, a recovery. Trace what each service needs from the others, then explore the buffers in an imagined city.

BUILT FOR THE CURIOUS

No specialist knowledge.
Just a reason to look closer.

Trace a path. Open a component. Follow a connection into another system. Every explanation is grounded in identifiable sources, and every model says what it leaves out.
