Using pixel rewrites for shape-rich interaction

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 organicwidgets, 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.
