This paper introduces new interactive ways to create, manipulate and analyze shapes, even when those shapes do not have simple algebraic generators. This is made possible by using pixel-pattern rewrites to compute directly with bitmap representations. Such rewrites also permit the definition of functionality maps, bitmaps that specify the spatial scope of application functionality, and organic-widgets, implemented right in the pixels to have arbitrary form, integrated with the shape needs of the applications. Together these features should increase our capabilities for working with rich spatial domains.
