We like smart and witty designs – you should know that by now – and we really like Shahar Peleg's smart thinking on the XO.
Really simple and really well done the XO is a Tic Tac Toe game and yes, you might argue that there are a ton of them out there, but this one is special as it is played on a mirrored surface and the X and O are only half of what they should be. Why? Well, you are playing it on a mirror surface, hence no need for the other half.
Yup, pretty smart.
