triple exposure. (the lumix has a multiple exposure setting: after the first pic, visible on lcd, you can take another, and after examining the double effect you can either retake the second or proceed to a third or keep it as a double. no more than three, though). Great way to not get anything done.
I really like this strange image, and this multiple exposure thing is all the more reason I am seriously considering the LX3. Thanks for the explanation.
