A couple months back a Minecraft enthusiast/do-it-yourselfer figured he needed improved seccurity in his apartment. "Unfortunately for me my building does not allow dogs so a big scary animal was not an option," he writes. Then, boom! he got this idea.

I don't think I've ever wanted to do a DIY project more than this one. It's a real life coin block lifted straight from Super Mario. So when you punch the bottom of the box, like Mario so often did, coins shoot out of the top (it even makes that classic sound!).
