Aperture 

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).

Aperture Science is a scientific research company founded by Cave Johnson. It was once called "Aperture Fixtures" but then named "Aperture Science Innovators" to make the shower company more hygienic. The company was actually focused more on science. Long story short, In 1998, the robot, GLaDOS, was turned on during the holiday, "Bring your daughter to work day". Unfortunately, GLaDOS became self-aware and filled the Enrichment Centre with neurotoxin, killing the scientists. Aperture Science was closed and turned into testing area, run by GLaDOS.

Word of the Day on November 3, 2026
Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.
