Electronic Popables

I thought it was more showing off what can be done in terms of using lights and various sensors, but this video also shows the possibilities of moving pop-up books which is useful to conceal all that goes on within the book (watch and you'll see). I thought as I watched it how it is a shame the beauty of the construction of the book gets ignored, but I suppose that happens with most pop-up books during childhood. Now I'm interested in it and curious about it I can really appreciate it. The end of the video shows the book a bit more, but it would be nice to see the pages being turned to see how the folds work.
