Silly, Play-Doh is no good for PCBs.

Actually, there's one company that came up with a way to make PCBs
using a play-doh like conductive goo. Mill/drill recesses in blank
(i.e. no copper) FR4 where you want "traces", squeegie the goo into
the recesses, bake so it hardens. Presto! Solderable traces, "plated
through" vias, etc, without etching.

Unfortunately, I couldn't find anyone who commercialized the process.
It probably would have cost too much for the equipment anyway :-P
