Field notes
The maths board combines a graph panel, a handwriting solver, a trigonometric circle, and 3D geometry; the site describes these as live objects rather than images. Its classroom-oriented storage details include atomic autosaves, rolling backups, and a trash folder for deleted boards. Five additional subject boards are announced on the page but are not yet released.
