Hmmm... On second thoughts, it might take you more than a couple of weekends!
What I like about it is the way there is an animation within the animation - the people holding the pictures move about and the pictures they are holding are themselves like a flickbook animation. Brilliant.
And while we are on the subject of clever animation, have you seen the Ultimate Dog Tease?
It's extraordinarily well done, yes? I assume they use something like CrazyTalk but for video.
Have you come across any quirky animations? If you have, leave a comment pointing me in their direction.
