RepulsionPak is a method to fill a container shape with deformable instances of geometric elements selected from a library, creating a 2D artistic composition called an element packing. Each element is elastic, allowing them to deform to achieve a better fit with their neighbours and the container. We start with an initial random placement of small elements and gradually transform them using repulsion forces that trade off between the evenness of the packing and the deformations of the individual elements.
