My kids were big LEGO fans and I can understand why. There are few other toys that offer so many possibilities. Worlds and vehicles and...all kinds of other objects are just waiting to be created. All you have to do is envision them and put together the right combination of pieces. Here's an intriguing video on how LEGOs are made in an almost exclusively robotic factory (a bit eerie, to be sure). Be sure to look for the LEGO sculptures (and what has to every kid's idea of a dream job) near the end.
