British artist Jon Burgerman's mantra is "pens are my friends". He's taken the traditional tool of the toddler and forged a career out of creating beautiful doodles out of felt tip pens. His work has appeared on hoodies for Kidrobot, surfboards for Ripcurl and even on a My Little Pony. Now you can get his "wonky, wibbly, odd, happy and dumb" style on your laptop, walls and car.
