Aperture Science ( http://www.aperturescience.com/ ) is a noted manufacturer of military shower curtains, but in recent years they have expanded their product portfolio significantly. These include:

• Fifteen Hundred Megawatt Aperture Science Heavy Duty Super-Colliding Super Button

• Aperture Science high energy pellet
• Aperture Science Emergency Intelligence Incinerator
• GLaDOS (Genetic Lifeform and Disk Operating System)
• Aperture Science Handheld Portal Device (featured above)
• And of course the Weighted Companion Cube.

All of these things were developed at their premier research facility, "The Enrichment Center".
