One sheet of paper is the whole film: it fanfolds into a stack of printed dashboards, opens into the Acme mark, peeks open to show the anomaly on its inner face, and refolds into an envelope. Crisp creases, faceted shading, teal ink — coral lives only inside the folds.
The fanfold strip unfurls left→right, one panel per eighth note, each crease flashing a dashed line for 4 frames before it folds; the red-lined panel lands on the bar-8 downbeat.
Four blintz flaps spring open outward on the drop (power3.out), revealing the mark in the centre square; “Acme Pulse” slides up from under the sheet one beat later.
The tri-fold opens left→right; the third panel stops at a 30° peek on a snare, showing the coral inner face with the anomaly, holds 2 beats, then the “Roll back” tag lifts its folded corner.
The sheet refolds into an envelope — side flaps in, bottom up, top flap down on the downbeat — the mark seal presses on the tip and “Start free” slides out from under it.
Folding is a perfect metaphor for “hidden until it matters”: everything looks calm on the outside and the problem is literally on the inside of the fold. Paper feels precise and honest. Risk: diagonal CSS-3D folds are fiddly — pre-plan every hinge edge and keep text on panels that face camera.
Adapt to your product: Print your product's key screen onto the sheet and pick the one thing it surfaces as the inner face; any list-type UI (orders, tickets, builds) folds naturally into a tri-fold or accordion.
