Here was my entry into the 2010 OUSA Design Challenge. The challenge was to design a car or truck from a single uncut square. This subject has always been interesting to me and was the basis for one of my first origami designs. My design methods have changed substantially in the last 8 years since my first attempt, and it was refreshing to address the subject once more. This model was folded from 10" Kami. You can find diagrams for this model in OrigamiUSA's online magazine, The Fold.
