RE: ATM 12 point mirror cell - examples

["McHatten, Shawn" <Shawn.McHatten@aliant.ca>]

Hey Tom
	Umm? I don't understand. Why must the platforms be three points (or triangular). This 12 point designs looks perfect for three squashed diamonds. Each made up of three outer ring points and one of the inner ring points. Collimation bolts go in the middle of each of the diamonds. 
	Hmmm?? Now I got something ELSE!! to read up on :). I obviously don't understand mirror cell design :).

I've updated my web page at:
http://overton.tamu.edu/aset/krajci/
specifically
http://overton.tamu.edu/aset/krajci/cell-12-pt/cell-12-pt.htm

Please let me know if I'm correctly laying out some useful, general design 
principles.  

Here's the $64 question - which of my two versions is better...or are they 
equivalent?

Thanks in advance,

PS.  I'm still digesting stuff on compliant hinges, main mirror focusing, 
etc.  Once I get firmer ideas about it I'll post them.
