A lovely little scientific research and development company enlisted by the American
MoD to produce shower curtains, among other intra-dimensional projects. Responsible for the production of the Genetic Lifeform and Disk Operating System (GLaDOS), the Aperture
Science Handheld Portal Device (Portal
gun, if you prefer), and many, many innovative iterations of the world-
famous shower curtain, Aperture are secretive in their operations and productive in their exploits. Future projects include life-enhancing gel, spherical personality buddies and tractor beams (or excursion funnels).
