Some people like to ruin their coffee with things like milk and sugar, others want their coffee black. But Australian artist Mark Poulier seems to be enjoying his morning brew with a lot of ink and a little imagination. Mark specializes in drawing architecture, but recently, he's been experimenting with coffee cup art. I really like his Leaning Tower of Coffee Cups. Intricately detailed, stacked and leaned properly — the paper cups look just like the Leaning Tower of Pisa. To see more awesomeness from Mark, be sure to check him out on Instagram.
