As a method of applying structure to my exploration of folding paper as a shape-changing interface, I am currently exploring different types of folds that allow for change along different dimensions. To begin I am looking at length, width and height. I want to identify different paper designs that support change along these dimensions, both alone and in combinations. For example, I am exploring paper designs that support shape change along length/ width/ height alone, length increasing as height decreasing, and width increasing as height increasing. The idea is that this will begin to form the basis of a paper-folding toolkit for building physicalizations, from which different dimensional changes can be selected as desired. The following folded or interlocking paper shapes represent a first step towards this goal. I have started to classify them by diving them into single dimensional changing shapes (which allow for a shape change along one dimension) and multi-dimensional changing shapes (which allow for a change along two or more dimensions).
