§ 01The Idea

Not a puzzle app with paintings in it.
A living museum where art appreciation begins with play.

Famous works arrive in fragments. You return them to a quiet gilt frame, piece by piece — no coins, no confetti, no streaks. When the painting is whole, Cadrelle opens around it: the story behind the work, the details worth noticing, an optional quiz, connections to other artists and periods. Tomorrow, a new highlight. This month, a new exhibition. Return for a few minutes with one painting, or an evening with a century.

§ 02 · i Restore — on finishing a painting
Restoration

The work returns in pieces.

Fragments gather as you move them. A painting reveals itself slowly, then all at once. Difficulty is yours to choose — a quiet few minutes, or an absorbing hour. No coins, no confetti, no noise — only the work returning to its frame.

Curator’s notes

Learn to look more closely.

When the frame is whole, the painting opens. Read the story behind the work, notice the details that matter, follow connections to other artists and periods, or test your eye with an optional quiz. What begins as play becomes a more attentive way of seeing.

Daily & monthly

A museum that keeps changing.

Cadrelle is shaped like a small cultural institution, not a static library. Each day, Today’s Highlight brings one work forward. Each month, a new exhibition opens around a single idea. Return for a few minutes with one painting, one story, one way of seeing.
