Inkboard
A teaching-board recorder that keeps handwriting as data instead of baking it into video.
Problem
Recording a whiteboard lecture normally bakes the ink into pixels forever, so it can't be searched, resized, translated, or re-styled later.
Outcome
Early-stage, M0 scaffold and proof of concept done. The board stores typed text, LaTeX math, ink strokes, and shapes as structured data, and only renders to video at export time.

Notes
You draw and write on an iPad with Apple Pencil while a facecam records you, for tutorial and note videos. Ink renders locally and instantly on the iPad, then replicates to a server over the LAN, so the board stays usable and precise even before anything gets exported.
