Headspin Storybook gives you a pop-up book and tasks you with turning the right-hand page into a mirror version of the left. All you do is click on the pop-up objects to flip them round.
It is. Until the distinguishing features of each object become smaller and smaller, the sheer number of objects overwhelms you, and the strict time limit urges you into a mess of frantic clicking.
Not so easy now, is it?
