I know it has been a while since I haven't written an article there. But I am quite busy at work, and I spend some of my spare time developing an application that runs on Android : Memory des Nombres
It is a game based on the Memory designed to help young children (between 4 and 8) to learn reading numbers... Yet it might be quite challenging for grown ups too. Do not hesitate to check it out and try to rank at the first place ;)
