A signature interaction
The Deck Visualizer
Reading about a cut is one thing — watching the cards actually move is another. This teaching-first 3D deck lets you split, cut, deal, and reveal, so the method stops being abstract.
Dealing the deck…
selected key card
See the state
The pack, the selected card, and a key card are always visible and labelled.
Watch it move
Split and complete-cut to see why touching cards never separate.
Reveal the secret
Turn the selection face up to confirm where it ended up.
Built for learning, not spectacle
Every animation favours clarity over flash: slow easing, clear highlights, and a 2D fallback for reduced-motion and low-power devices. Drag to rotate the table; the controls below the scene narrate each change. It's the same engine we use to diagram individual tricks.
