Perhaps not necessarily at home yet, but I was reading in "Electronic 
Design" (a trade magazine I get at work) about Xerox working on a 
semiconductor inkbased on a poly compound that can be used to print 
electronic patterns.

Supposedly, they can actually "print" working transistors (however, 
slower and larger than the silicone counterparts).

This will be an emerging technology, but it isn't quite ready for 
prime time.  In the mean time, without chemical etching, one could 
still:

1. mechanically etch (milling)
2. wire wrap
3. simply solder the components together (make modern art) ;)
4. use your imagination....

Of course, some of these aren't PCBs.....oh well...
