I've been getting a kick from this awesome study on brand and logo simplification, Unevolved Brands. ImJustCreative poses the simple question: can we still recognize these well known brands with simplified to circles? It's a great idea executed wonderfully. I have been stumped on quite a few of them, but still find it fascinating how quickly some come to mind even in such an abstract state. Thankfully, we've been given some clues on a number of them. Give it a shot, and see how well you do!
