Restore this masterpiece
The Bookworm
Museum Georg Schäfer, Schweinfurt
Rebuild The Bookworm one luminous fragment at a time. In Mosaic Atelier, every famous painting returns as a handcrafted stained-glass logic puzzle — no timers, no ads, just calm deduction.
The story behind The Bookworm
Painted around 1850, Carl Spitzweg's The Bookworm shows an elderly scholar perched high on a library ladder, so absorbed in his book that the world beyond has ceased to exist — a gem of German Biedermeier painting: intimate, witty, and quietly satirical. What the canvas does not announce is that Spitzweg himself was a pharmacist who only took up painting seriously in his late twenties, largely self-taught.
The Bookworm as a stained-glass puzzle
Mosaic Atelier turns Carl Spitzweg's c. 1850 masterpiece into a set of stained-glass logic puzzles. You place coloured glass fragments into valid regions using pure deduction — the same satisfying reasoning as a nonogram or a logic grid — and as each puzzle resolves, another pane of the painting lights up. Finish the world and the whole artwork glows back to life.
