There is this new Lego theme called life of George. It's so cool! You buy this set with bricks and a special base plate. Then, with your iPhone or iPod touch, you go and download the app Life Of George. What you do is you open the app, you have all the menu and stuff, then you select a challenge. What happens is that you get a model to make and a certain number of time. When you are finished, you place the model on the special base plate. Then, take a picture and you completed the challenge!
