[~OT] Tinkers Guild (was :Re: Are Aluminum Mirrors in reach of the ATMs?)

["Matt Considine" <matt@considine.net>]

For what it's worth, all the project columns (from different 
fields) from Sci Amer are available on CD-ROM from Tinker's Guild
	www.tinkersguild.com
It costs about $90 (as I recall) and has been compiled by the author 
of the book mentioned below.

I have no commercial interest in it, am not related to the author, 
blah, blah, blah.  I just like the CD.
