Room IV / Crease
Fold Clock
Exact local time
A single sheet bends along hour and minute creases. Facets, exposed reverse faces, and their shadows build one relief rather than four changing cards.
Construction
Solid dark creases rise toward the light. Dashed violet creases recede. The four digits choose their slopes, but all facets remain joined as one sheet.
How to read it
The dark cuts across the raised central facets give the hour and minute. Shadows show which faces lift from the gallery floor.
One sheet
No panel flips independently. A change to any digit alters the tension and angle of the whole sculpture.
