The ancient art of doodling has been around for thousands of years. Depictions of wild beasts on cave walls, funny little carvings on age-old artefacts - we've been at it a while. So what better way to celebrate this time-honoured tradition than by doodling while you dump? Fill a fish tank, illustrate the alphabet, envision outer space - whatever takes your creative fancy. Sit back, relax and prepare to make your masterpiece.
