I am looking for a copy of the following 


W. Thurston, Groups, tilings, and finite state automata, AMS Colloquium Lecture Notes.


I see that a lot of papers in the tiling literature refer to it but I doubt it was ever published. May be some notes are in circulation ?


Does anyone have access to it? I would be extremely grateful if you can send me a copy or tell me where can I find it. 



Lecture notes by Thurston on tiling
Unfortunately, the original to this is hard to locate. It was distributed by the AMS at the time of the colloqium lectures, but they apparently didn't keep the files they used. At one time it was distributed as a Geometry Center preprint, but the Geometry Center is now defunct. I've lost track of the source files through multiple moves, computer crashes, etc.


What I have is a scanned version of the Geometry Center version that is legible but not beautiful, which I can forward by email


Bill Thurston


ADDENDUM:
Renaud Dreyer told me of an online scanned version I wasn't aware of, which appears to be better quality than the one I have:
