This document discusses EightShapes' journey to prototyping with HTML from PDFs. It outlines different projects the company prototyped, from megamenu to complex apps, moving from sketching to wireframes, UI comps, and HTML prototypes. The speaker, Nathan Curtis from EightShapes, presented at a UIE virtual seminar in April 2011 about their process of communicating richer interactions and user experiences through HTML prototyping rather than static PDFs.
