Whilst doodling is nothing out of the ordinary, perhaps doing so on a series of polystyrene cups and selling the results for hundreds of dollars is a little more remarkable. That's exactly what California-based Cheeming Boey, a 31 year old artist and animator has done which is now taking the Internet by storm. According to an interview over at the Sharpie blog, Boey came up with the idea when he was craving to sketch but lacked the necessary paper, so he simply started using a cup which was discarded on top of a rubbish bin. He quickly knew he was onto something, and before long he was filling his apartment with excruciatingly-detailed examples of art - waves, animals, noodles and more profound works such as this. All this with a simple Sharpie pen; nothing more than a permanent marker. His friends, as you can imagine were suitably impressed, but the turning point came when a friend remarked 'Sure, they're nice, but who'd pay money for that?' according to an interview with the OCRegister - his stubborness was about to be rewarded. Boey made his way to Laguna Beach, armed with a few choice examples of his work. He ended up at Marion Meyer Art - a contemporary gallery showcasing artists from all over the world. Meyer was drawn to the passion and energy evident in Boey's art, and he was consequently invited to display his cups in the gallery - where they sell for $120-220 and was word spreads, considerably higher. You can see many sets of his coffee cups on Flickr here, or watch this stunning timelapse video below, which demonstrates how Boey puts the drawings together:
