Absolutely wonderful! While it was fun and engaging it challenged me on another level. I generally think about audio for narration, video, and sound effects (where it compliments or supports the learning). This made me think outside my usual developer/authoring perspective and consider, "Are there options I haven't considered yet?" Could they do the same (or better) job and engage the learner in a different way? Not for the sake of being different, but for the purpose of getting the learner to use their senses, (see, think, hear) to process the content, and thereby (hopefully) remember/learn/understand more. So, thank you for your wonderful example and sharing it with us all.
