My iPhone is so ancient that it’s positively Flintstonian, and I keep putting off buying a new one, because the functions I need my mobile device to perform remain simple and few. But I have just now glimpsed this new iPhone 5 case by Danijo, and its post-millennial psychedelic fabulosity has put me in another frame of mind entirely. It’s part of a collection of seven, all apparently based on kaleidoscopic images of Danijo designs. If it came in a dress, this print might be a bit much. But as a wild fastasia of color the size of your hand? Crazy good fun.
