It has won The Royal Society Young People’s book prize 2014.

Some images appear to move around, leaves glide down:

Frontal lobes – orange on the diagram above – learn to recognise movement

The blue cerebellum organises images and locates them, so that things appear that are not there:

Objects of the same size appear longer and shorter, bigger and smaller:

And the same colours can appear to be very different:

The purple occipital lobes recognise colour. (On the left, what appear more like brown and pink are the same red. On the right the central orange and brown are the same .)

The judges of the prize are all below 15 years of age.
