Useful website-
www.d-n-i.net - run by Chuck Spinney. Has the best stuff on OODA you'll find anywhere. Also, any folks close to Quantico can go to MCU and they'll let you dig through the Boyd archives with zero hassle...Can get video of the man giving a brief on the subject made into a DVD.
As to shaping your adversary's observation/orientation, that's very much at the core of Boyd's work. He was a devotee of Sun Tzu. Loved to quote Patton on "hold him by the nose and kick him in the pants." As was mentioned, he inspired the Desert Storm plan, of which half was the USMC pretend landing that fixed the Iraqis in place so the hail mary could loop behind.
Also key to remember that "loop" was a term Boyd hated. He preferred "cycle," which is much better reflected in some of his later (complicated) diagrams. Each portion feeds back and forward to the others. New information can preempt acting while you're making up your mind, causing a different observation, creating a different orientation, leading to a different decision.
