A classical calculus problem, the so-called Paper Creasing Problem, deals with extremizing the length of the crease formed when a rectangular sheet of paper is altered by folding one corner, say the lower right-hand corner, to the opposite edge. The length of the crease depends on the distance the active corner is from the upper left-hand corner. Using this distance as the variable, the problem naturally divides into several sub-domains, in which the maximizing and minimizing points may occur at interior or endpoints depending upon the dimensions of the sheet.

This sculpture formed by folding individual pages is an example of the variety of the three-dimensional forms which can be obtained by incremental changes in the length of the crease from page to page and by extending the points that can be used.
Longest Crease K

This sculpture is also formed by folding individual pages. It provides another example of the variety of the three-dimensional forms which can be obtained by incremental changes in the length of the crease from page to page
