It's the Easter holiday for us undergraduates, though I can't let that fool me into thinking I don't have any work to do. Because there is plenty of it.
In two weeks I will have handed in my work for the last time. Crikey. Anyway, this week I've been doing an editorial illustration for the Guardian's 'This column will change your life'. It's about how in order to learn a new behaviour, the desired action must be rewarded at random when it is performed. This illustration might not change your life - but it won't make it any worse!
