Greek Artist Petros Vrellis is a big admirer of Vincent Van Gogh, which prompted him to produce an interactive version of Starry Night. It took him a patience-sapping six months to produce the original PC version, where finger swipes redirect the painter's famous daubs into a light and sound show. Of course, there was such a clamor from users all desperate to have a go, that he managed to produce an iPad app in a little under a month. Now you can pick it up from the App Store at the source link, or head on past the break to see this new version in action (you really do have to see it).
