his design inspiration. His stated goal is to "find the principles in nature that make organisms be successful in their environment". Stephenson's design process progresses from sketch pad to computer graphics, to clay models, and finally to prototype models.

He credits curiosity, research, and innovation as key drivers to his design values.
