Not sure what it’s referred to as, but at the end of a free webinar today, Jim Womack shared a recent publication of his.  It looks pretty cool, and while it can be printed, has some videos that wouldn’t work well on paper.  Not sure if it’s accessible to the general public or if you had to attend the webinar (I might have missed that part, I had to sneak out to catch the first Pella Tulip Time parade of the year).
