That's awesome if I made something like that I am sure it wouldn't last long before someone would destroy it. My driveway is a 1/2 mile long and I cant see my mailbox from the house so I wouldn't know till probably the next day that someone had done anything to it.
Way cool. Mine is know where near that cool. But i did make it with leftovers. I've got to look in the scrap pile to see if i can come up with anything else here are pics of my 2.
