I really want to make something using conductive ink. I just went to Maker Faire and there was some project in which the resistance of the ink was determined by how wide the swath of ink was, and some object was waved over it—the object had two electrical poles, power and ground—and funny sounds were produced. The whole thing was connected to an Arduino. Anybody have any insight? Anybody know any good tutorials?

Is there any way I can do something like this using Arduino? Also, can I paint my circuit on wood?
That circuit uses
Atmega ATtiny 85 through-hole (DIP) microcontroller
You should be able to impement that with an Arduino without too much trouble.
can I paint my circuit on wood?
Not practical.the ink while conductive has resistance and so will not make a good connection. It is also tricky attaching components to it as you can't solder to it.
Really? At Maker Faire they painted on wood. They drove nails through the painted area and had alligator clips leading from the nails to the inputs on the Arduino.
What material is more practical then?
"They drove nails through the painted area and had alligator clips ..."
Sounds very Steam Punk-ish ...
