People tinker, hack, fix, reuse, and assemble materials in creative and unexpected ways, often codifying and sharing their production process with others. Do-ityourself (DIY) encompasses a range of design activities that have become increasingly prominent in online discussion forums and blogs, in addition to a small-butgrowing presence in professional/research forums such as CHI. This workshop will explore DIY practice from the ground up--examining DIY as a set of methods, communities, values and goals and examining its impact in the domains of traditional crafts, technology development, and sustainable design.
