LEDs!!

Having had trouble with audio, we've gone back to light effects, using a potentiometer and different coloured LEDs.

Here, the idea is that the "mother" doll is surrounded by her "children." When her back is turned to one, it "talks" (Mouth flashes). The one she is facing however, stops "talking" and it's checks glow red, embarrassed for having being caught.

In this scenario we have a potentiometer working to determine which lights go when. Furthermore, the reaction is staggered so that the dolls on either side of the one who is chatting, are talking too, but not as much (i.e their mouths are flashing but at a slower speed). This also happens to the two one either side of the one who is "caught" - their cheeks glow red, but not as much. When the mother turns to the next doll, the reaction follows suit.
