A handful of good fast prototyping design and style images I identified:
ITU Fast Prototyping Workshop

A speedy prototyping workshop for Master of Interaction Design and style students at ITU. An introduction to rapid prototyping as a idea and as a practice, both in the quick and dirty sense (using obtainable components to accomplish proof of concept) and by way of awareness of tools available such as the CNC machine, the Rep Rap machine, and use and expertise of components, processes and communities. Element lecture, portion hands-on prototyping total with proof of concept from every single group.
