My hammer. :D
'Draw your favourite tool' prompt. Two foot by three, and still rather cramped. Spraypaint. Which does throw up the question: If this is drawn in paint, is it a painting or a drawing? (Although, to be honest, I feel it's more of a painting due to technical restraints - the nozzles I was using made a thin line, but at a low pressure, so I couldn't actually draw - I couldn't make the marks and movements at a speed that seem to qualify as 'drawing' to me. It's a linear quality thing, I think.)
