What you are looking at is a magazine fed semiautomatic rifle made completely out of Legos and 3 rubberbands. It shoots Legos.
I stopped counting the number of hours I have invested into the thing. You'll be happy to know that there is still room for improvement. My kids, of course, have lost 40% of their legos, which used to be mine.
In other news, I still have to a few more coats of finish for my dressing table. I will likely complete that in a week.
