have just been in a nursery where they had jigsaw puzzles that made the noise of the animal shown when u put the put the puzzle piece in the correct place (also if you just held your hand over it (must be a light sensor or something). however i forgot to ask where they got it from and it had no markings on it to say so. does ANYONE know where i can get them from?? would make lovely present for my niece. cheers.
