The form of this work is an iPhone/iPod/iPad application which functions as a sort of photo filter. The user can subtract, or better yet, abstract a simplified geometric shape from the picture. This shape is uploaded to a database where all shapes of all users are collected. This collection is then segmented into different classes into which the collected shapes are 'stored'. The segmentation is done based on all the shapes present. So the collection is dynamic and changes through the collected shapes.
