When most of us commute to work on a train, we're more likely to read a book or listen to some music than create absolute art masterpieces on our iPhones or iPads. That's what Seikou Yamaoka does anyway. He's a humble office worker from Tokyo who uses these Apple devices to make the most incredible finger paintings with the ArtStudio app. You'd mistake his work to be painted with oil or acrylic paint, not by using his fingers on an iPhone screen. As you can imagine, Seikou has become an Internet sensation and one of his videos - where he creates his own version of the famous 'Girl With a Pearl Earring' by Johannes Verneer - has gone viral. You can see more of his beautiful work over on his website.
