So this is the second time I’ve written about a clever project by Rethink, the Toronto-based ad agency. But seriously, these folks come up with some cool things. This isn’t exactly new, but I hadn’t seen it before so I figured it was worth posting. To promote ICOGRADA’s Design Week 2010 conference in Vancouver, Rethink created this animation by designing over 2,200 custom “bills” and feeding them through a money counter. It’s the flip book of the future! You can watch the video of their animation at the end of this post.
