I seriously think there should be scaled-up version of lego bricks -- something you could build life-size stuff out of, like playhouses and toy cars kids could sit in.

And think about the possibilities if those bricks could be used to make simple furniture (Tired of your couch? Take it apart and use the cushioned bricks to build a set of comfortable chairs just in a few minutes!) or decorations on your backyard!

Of course, you should look out for your asshole neighbor stealing your bricks to his contraptions.
