Back in 2004 architecture students weren't using 3D visualizations much for their concepts. (At least not at the University of Michigan) A student and friend in the Taubman College of Architecture and Urban Planning (TCAUP) was exploring unique forms and shapes from which to derive architectural spaces. Some of these were quite "different" such as ironing ketchup and mustard between two sheets of paper to see what patterns emerged. From those experiments she came to a design but needed help in visualizing it. I then worked with her creating the necessary geometry and lighting for her final piece and being a wall to bounce ideas off of as the design evolved.
