Originally designed to keep employees, test subjects, daughters from BYDTWD employed at Aperture Science for indefinite periods, GlaDOS has invented the Continued Employment Initiative, Which allow vacant cores, turrets or cubes to be achieve sentience and allows the employee to continue there work. The body is then stored with unused test chambers.

The device also has a secondary purpose, it allows for mind switching! Although more testing must be done before the device is completely ready for continues mind switching. Current test subjects sometimes find that one brain may not exactly jump over to the replacement body. This seems to happen mostly with A subject. The good news is it doubles a persons thinking power. The bad news.... well, its like living with a roommate... who you are duck-taped too.

By the way, I decided to swap minds with Rick. While everyone loves the Space Sphere's willingness to go into space, or the Fact's spheres knowledge. Many people do not like the Adventure Sphere that much. I mean, he has a black belt in Karate, Jarate, and even the bedroom.
