When I first looked at the thread title, I thought you are talking about signs of intelligence. But then I saw you are talking about Texas....
Now hey there! Dell and Texas Instruments are both based in Texas and of course NASA mission command is in Houston.
Don't forget about AMD, Bell Helicopter, and what used to be Consolidated Aircraft/General Dynamics (home of the B-36 and F-16). Dr. Pepper is also a Texas invention.
