Portal GLaDOS Ring
Genetic Lifeform and Disk Operating Systems now come in finger-sized. GLaDOS rings make it easy for all to show off their loyalty to the eye of Portal's most beloved piece of sociopathic artificial intelligence. Created by Shapeways designer Quatro, the jewelry comes in 11 different material options, presumably to suit all tastes and budgets. Pictured in White Plastic ($17.80) for DIY painting, buyers may also choose to upgrade to solid Stainless Steel, Silver, Antique Bronze, and Gold Plated rings.
GLaDOS adornment default size is 20.32 mm in inner diameter, though customization is also available in US ring sizes 8 to 13. While wearing GLaDOS Jr., please beware of assuming a passive-aggressive, narcissistic edge, similar to that displayed by 95% of the population of Seattle. Also be warned that the ring may inject you with a lethal neurotoxin.
