HAHA! Time to build the unstoppable army!
Unfortunately, I don't own a single Lego brick at the moment. However, if I had the extra money and a little more extra room in my house, I would probably by 10 of those assorted brick boxes (they come with what, 500+ pieces each or something like that?) I love playing with Legos! People say that they are a past time, but hell, there are still practical uses for them. The engineering class at school uses them on occasion, and my computer class even has actual working Lego robot kits that you have to build and program yourself!
Until then, I'm stuck with this: http://factory.lego.com/
Its pretty fun, but you can't manipulate the bricks like you can in real life.
