Wingwarping to the extreme – current wings use leading and trailing edge slats to change their shape in order to create more lift at different angles of attack (angles of aircraft and thus wing pitch into the airflow). This usually creates 3 seperate surfaces for control, but if you look at the way birds reshape their wings, it’s a much more fluid and precise process.

So these guys are building morphing wings on aircraft with wing spans less than 2 feet (probably due to structural integrity issues). It’s a cool beginning to this technology, and the site has videos etc.
