It takes a certain degree of skill and a whole lot of dedication to build what Mindstorms user hknssn13 built: a machine made entirely from LEGO that folds paper into airplanes and then launches them! Granted, it’s a relatively simple thing to do–if you’re doing it with your hands. It’s a completely different story when you’re trying to automate the process with nothing but a LEGO machine.
About 6,000 to 7,000 LEGO bricks were used to build the paper airplane folder and launcher. The moving parts at the bottom required two NXT Intelligent Bricks, five NXT servomotors, four NXT color sensors, and a Touch Sensor Multiplexer.

Could have done without the music, but all in all, a cool concept.
