When the company I work for was located in Cambridge, MA there was an interesting company across the street called Thinking Machines Associates. I dropped by at lunch time to drop off my resume and fill out an appilication. I was told there were no openings and my resume was refused. I never gave it much thought after that until I saw the company named in Rainbow Six by Tom Clancy. It was an NSA front working on encryption supercomputers. No wonder they were open to the public.
