Kirigami is a program that allows you to edit wedges, which correspond to the wedges of paper which result after folding a piece of paper. The editing that you perform is to cut polygons out of the wedge. You can then see the figure that results when the paper is unfolded. This figure is displayed in the upper left of the screen.
In addition to editing a single figure, you can create and edit an entire stack of figures. This stack is displayed in the upper right of the screen.Help for editing a wedge
