How the catalog works

01

One card, one encyclopedia

Each card is a whole site about a single subject, from clocks to shipwrecks, with its own look and its own way of telling the story.

02

Working, not pictured

The drawings are computed from real models. Shadows fall where the Sun would cast them and pendulums swing with the right period. Push on them and they answer.

03

Filed one at a time

Cards stamped Open are ready to read. The rest are being written, and new ones are filed as they are finished.
