The Eyeliner system is a whole new way of projecting video. All of the images used on a Musion system are holographic foil 3-dimensional images, but projected as two-dimensional images (2D3D) into a 3D stage set. The mind of the audience creates the 3D illusion. This means that production costs are minimal, needing only single camera lens for filming and single projector for the playback - hence the phrase, GOGGLE FREE 3D.
