Today's UI design theme is analytics. Analytics is used to tracking how parameters vary overtime, so that people can analyze its trend.
I've been working on an interesting mobile app concept that tracks some game players' performances, so I'll just use it as my practice today. In the mobile, you can see the player's rank, number of wins and losses, as well as a rank trending graph -- that's the analytics part! By default you can see the trending graph, if you touch it with your finger, you can see what rank exactly this player was at.
I built it in Axure. The hand was created in Adobe Illustrator.
