Back-lit view of paper and foil micro-controller board

After visiting The Hacktory’s “Soft Circuit” event, PJ and I were inspired to take a stab at making some micro-controller circuits using alternative, “high/low tech” approaches.  PJ made an MCU circuit using conductive paint (has potential, but needs some tweaks).  I opted to try a circuit board using metal leaf.  That happened to work on the first shot — although careful scrutiny of the picture on the left suggests there was some luck involved (there are holes in the circuit that come dangerously close to wrecking it).
