Merlin shows the Leonardo virtual reality kit that allows one to control 3D images displayed on the screen, using their proprietary controller that uses 3 IR sensors to monitor the position. The software also allows for direct import of 3D CAD files, supporting output to 3D printers. Based in Budapest, Hungary, the Leonardo sells for US$1000 and uses an open API that can be used for creating 3D games. The kit includes a pair of 3D glasses, the software suite and the wired controller.
