Cynthia had a cuckoo clock. Every hour the cuckoo came out of its house and sang its song. She noticed that the sound it made was slightly flat, so she decided to tune it.
   The next time it came out, she was there to catch it. She made a few adjustments before letting it back in. She waited an hour for its next appearance, but it still sounded out of tune.
   She waited another hour so she could have another go at tuning it, but the cuckoo saw what she was up to. It came out ten minutes early and she missed it. After this, it was impossible to predict when it would emerge from its house, and it always came out very quietly, before singing its song very quickly and going back inside.
   She couldn't watch it all the time, so she trained her dog to sit in front of the clock and bark every time the cuckoo appeared. She was able to catch the bird again, and she made another attempt to tune it. The sound still wasn't quite right, so she kept the dog at his lookout post.
   But the cuckoo started looking behind the dog, as if there was something there, so the dog turned around. The cuckoo managed to train the dog to turn around every time the doors opened.
   Cynthia found the solution in a dream...

   in a dream...

      in a dream...

         in a dream...

She had a smoke machine. She used it when she had important announcements to make or when she didn't want to see her feet. (It was a dream about not wanting to see her feet). She was with some friends. They were happy to focus on the drinks in their hands when they couldn't see their feet. They left themselves for a while, and when they came back there were robins nesting on their heads. They didn't know whether to ask them to leave or just try to ignore them. But the problem was solved for them when a falcon came along and scared the robins away.

   Cynthia woke up and said, "Ben's falcon!"
   On the following day she went to see Ben, who had a falcon. He was training the falcon to be a mime artist. Cynthia saw the bird's act and said, "He looks as if he's banging his head against a wall."
   "No," Ben said, "he's... nodding in agreement."
   "He's nodding in agreement with what I said about banging his head against a wall."
   "No, he's..."
   Cynthia's plan was the use the falcon to scare the cuckoo into submitting to being tuned, and the cuckoo looked terrified when it emerged from its house to see a falcon right in front of it. But the next time it came out it looked more curious than afraid, and eventually it just seemed to be thinking, "That falcon looks as if he's banging his head against a wall."
   Cynthia found the solution in another dream: build a robot to sort the whole thing out. She hasn't actually built it yet, but she's confident it will work. In her dream, the robot scared the falcon from her head.
