Sketch Book

a book drawn in thin pen strokes, seen from straight above, so all there is of it is a cover. hover it and the camera swings down to an isometric view and it turns out to be a cuboid, and press it and the cover opens and the first page writes itself.

key insight: the book is four boxes and the camera is two angles under an orthographic projection, so the cover and the cuboid are one drawing at two poses. every line is a filled ribbon whose width is the pen's pressure, landing heavy and lifting thin, and every wobble is a share of its own line's length, so a side turning edge on takes its scribble with it.

the drawing inks itself in the order a sketch is built when it first comes into view, and redraws its wobble about twelve times a second while the book moves.
