Creativity support tools are set an especially difficult task when they are applied to art/science collaboration. Not because of any fundamental incompatibility between the disciplines, but because creativity support tools are rarely supple enough to manage dramatically shifting requirements at various stages of design or handle the diversity of artifacts that might be generated. Traditional methods of evaluation of collaborative support tools may not address these aspects. This workshop aims to examine three specific areas open to expanded modes of evaluation; the social aspects of tools and tool use, how artifacts are created and manipulated in support tools, and how the expanding contexts of art/science collaborations may be rapidly changing support tool requirements.
