Kimio Kosaka soldered together quite a unique Arduino clone. The entire board is done freeform, with no PCB whatsoever. Based on a Metaboard, Kosaka designed and printed the layout in Eagle CAD. He used the printout as a template to bend steel wires into place to make the connections. Despite using a method that’s known for its delicacy, the final product looks surprisingly robust.

These freeforms are all very pretty, but watch out. Without the full or partial ground plane a PCB provides, your signals can get ragged and even go wrong.
