The idea was revealed at a December workshop on robotic algorithms in Nice. Instead of creating a casing and then laboriously filling it with electronic circuit boards, components and switches, the plan is to print a complete and fully assembled device."
I once had a dream as a child of a paint by numbers set, where the paints had electrical properties. By sending electric currents through such a painting, you create a simple electric circuit capable of doing anything simple circuits are capable of. A few layers of the right "paints" would make a resistor, capacitor, or transitor. Light emitting diode paints could even light up as a display for a clock or a simple computer. I had even considered the possibility of putting these paints in a printer. Sometimes I think that childhood imagination is wasted when it isn't pursued.
I am glad to see that I may have been on to something really cool.
