We've seen all manner of jaw-dropping Lego creations, but some of the best are creations that create. This machine fashioned from the fantastic plastic creates and launches paper airplanes.
Created by Mindstorms user hknssn13, this mini factory was made from 6,000-7,000 Lego bricks and measures 59 inches long by 15 inches wide. Not exactly portable, but it works.
As seen in the sped-up vid below, it automatically grabs a sheet of paper from a paper tray, then puts it through a series of folding movements, giving it wings.
It finally slides the plane onto a mini launchpad, and sends it hurtling off into the air. The video doesn't show how well the thing flies, but it looks decent.
The plane factory is an improvement over an earlier version that needed a hand now and again.
Version 2 has a long list of components, including two NXT Intelligent Bricks, five NXT servomotors, four NXT color sensors, and a Touch Sensor Multiplexer.

If only it could crank out a personal jet.
