This concept from designers Ami Drach and Dov Ganchrow is called +/- hot plate. PT hit it back in 2009, but it seemed worthwhile to bring it back around, again, in honor of Ceramics Month.

The plates are silkscreened with conductive inks to create circuit traces, in this case simple resistive heating elements arranged in artful patterns. If the traces will hold up to soldering, adding SMT components would be a cool n + 1 move.
