This project demonstrated how basic display can be converted to display stereoscopic images that don't require any extra glasses. A simple lenticular lens can be 3D Printed using a resin based printer and placed on top the display. Several images are interleaved but only one is visible from a each viewing angle. Since the eyes look from different angles two different images can be displayed creating a stereoscopic image.
