Traditionally, the notion of home crafting connotes the use of "low-tech " materials and techniques; but increasingly, the once-distinct worlds of crafting and computational media have become integrated, to the mutual benefit of both cultures. In this paper, we discuss a wide range of recurring issues in the integration of crafts and computation, drawing upon a variety of related research projects. In particular, we explore the ways in which attention to computational crafts can encourage a productive re-examination of such notions as programming languages, computer architectures, and peripheral devices. Keywords. Computation and crafts, HyperGami, HyperSpider, computationally-enriched craft items.

Computationally-enriched crafts are activities that blend the advantages of computational media with the affective, social, and cognitive affordances of children's crafts. In this paper, we describe a design application, Popup Workshop, whose purpose is to introduce children to the craft (and engineering discipline) of pop-up design in paper. We describe the fundamental ideas behind computational crafts in general, present our application in its current implementation and offer a scenario for its use, explore the particular ways in which pop-up design serves as fertile ground for integrating computation and tangible design, and discuss our early pilot-tests with elementaryschool children, as well as ongoing and related work.

The traditional view of the “home computer ” is as a selfcontained appliance: computation, on this view, is something that takes place within a desktop box, and that produces interesting visual effects only on a screen. In this paper, we argue that one can alternatively view “the computer ” through its tangible effects on larger settings: that is, the computer can be imagined as the heart of a creative workshop centered within the home or classroom. The advent of accessible fabrication devices, as well as small computers that can be embedded in craft items, permits users to think of the room at large as a place in which computationally-enriched or computationally-designed "exhibits " of various types may be displayed. We illustrate this idea with a variety of projects undertaken within our laboratory. Author Keywords Computational crafts, fabrication devices, embedded computation. ACM Classification Keywords H5.m.

As I write this sentence, I am glancing over at the color printer sitting beside my screen. In the popular jargon of the computer industry, that printer is called a "peripheral"—which, upon reflection, is a rather odd way to describe it. What, precisely, is it peripheral to? If the ultimate

This paper describes our work on a computational tool for the design of mechanical elements suitable for use in automata (mechanical toys and sculpture). The purpose of the tool is to permit students to create customized mechanical components (such as cams); to combine and simulate sets of components; and to "print out " the components on devices such as laser cutters that realize the designs in wood. We discuss the educational rationale behind our work; describe the current (still early) state of our system; and explore the relationship between our work and larger issues highlighted by work in "computational crafting."
