I managed to manually create a iBook Author Widget which works quite well (despite the fact I get a white flash while the widget loads) … but I would like to include this type of effect within a Hype project.
I experienced some glitching with Stephens version, probably because the way you relatively decrease and increase group/image size and position. I would check out h_classen’s version instead GL29, even if it’s quite hard to understand the way it works and how it’s coded; the animation is seamless on my end.
