Matt Whitlock, who helped make one of the world's first Bitcoin ATMs, is at it again. In a video posted on to Vimeo, he showed how using the calculator once only used for high school geometry and a 12-sided die makes a secure address for your Bitcoin account. The video self-explanatory. Load up your calculator with the code, roll it 72 times and enter the number rolled into it. After that, the calculator pumps out a private key and address.

Well, that was one of the more unexpected "you mama" joke: Your mama is so fat that she shows up in a post mentioning only your room!
I want to note that just in case someone thinks so: You can not roll two 6-sided die and add them together and get a 12-sided dice - first of all you cant roll 1 and you roll 7 way too often. What you can do is have two rolls of a 6-sided die. Say you first roll x and then y. If y is even you rolled x otherwise you rolled 6+x. This gives you precisely 12 different equally likely outcomes.
