In recent years there has been an upsurge in the publication of 'interactive' books, designed to spark our creativity. Colouring books for adults, as well as my teenage daughter's current favourite: ''Wreck This Journal,'' seek to tap into our creative side, whilst promoting mindfulness and relaxation. By actively encouraging us to slow down and look at the world around us, books like these enable us to take time out of our busy lives and just enjoy the present moment. And this method must be working, because they are proving incredibly popular. I was intrigued, therefore, at the idea behind ''My Year in Small Drawings,'' which invites readers to create a visual diary of the world around us by creating a series of small pictures on a given subject.
