I have always loved Legos.
In fact, when my friend got "too old" for her sets of Legos, I promptly bought them all from her (i.e. got my parents to buy them for me for Christmas). Now I have a giant bin in our basement just waiting until my daughter is old enough to really get into them.
So, you can imagine how excited I was when I saw this.
I guess these people go out and fix public spaces with Lego constructions. This gives me all kinds of ideas for fix-it projects around the house ...
