Building off of Jakub's sketches, here is another iteration on the experience threads.I explored placement alternatives for the experience threads within the FluidIA interface and several options for the detail of the experience threads themselves (tabs, nested tabs, boxes that highlight the current frame). Also, I introduced a new paradigm for explaining the function of the experience threads themselves. Think of the experience threads as processes. There may be multiple processes within a project. Each process has several steps, which can be thought of as frames. Each frame has a mockup associated with it. The detail sketches illustrate this hierarchy.
