Xerox PARC makes way to print circuits on flexible items.

I hate to say it, but this isn’t new.  I remember (had bookmarked) some initial work folks did (http://www.instructables.com/id/DIY-Flexible-Printed-Circuits/ and http://www.pabr.org/pcbprt/pcbprt.en.html  ) in 2008ish by converting an old phasar for the opensource community.  Given this method was subtractive instead of additive….It was a start.
