Two parallel paths of concept sketches of a toy helicopter in skWiki. skWiki supports multiple, co-existing revision histories for the same multimedia object. This is possible using paths that track changes over time and allow users to preserve complete operation history.

skWiki is a web application framework for collaborative creativity in digital multimedia projects including text, hand-drawn sketches and photographs. skWiki overcomes common drawbacks of existing wiki software by providing a rich viewer/editor architecture for all media types that is integrated into the web browser itself, thus avoiding dependence on client-side editors. Instead of files, skWiki uses the concept of paths as trajectories of persistent state over time. This model has intrinsic support for collaborative editing, including cloning, branching and merging paths edited by multiple contributors.

Juxtapoze is a clip art composition workflow that supports creative expression and serendipitous discoveries in the shape domain. It achieves creative expression by supporting a workflow of searching, editing and composing: The user queries the shape database using strokes, selects the desired search result and, finally, modifies the selected image before composing it into the overall drawing. Juxtapoze facilitates serendipitous discovery of shapes by allowing multiple exploration channels, such as doodles, shape filtering and relaxed search. Results from a qualitative evaluation show that Juxtapoze makes the process of creating image compositions enjoyable and supports creative expression and serendipity.
