We were prompted to design and build an object that either flew or gave the appearence of flight. After a lot of brainstorming, we decided to make wearable wings that did not fly, but did extend and flap. After much consideration, we discarded the idea that they would extend, and instead decided to make them flap like actual bird's wings.
Our final design was a laser-cut wing made of thin wood that had leaf-like designs on it. The whole thing was made of wood, and it was not covered by a fabric of any sort. This design added aesthetic and reduced drag. It was slightly heavier, but that was not a problem as it did not need to acutally fly.
