This is a fair dice site including the verifier so you can see that the results are fair and not tampered with. I wrote this as a way for me to learn Tornado. In addition, I'm using KnockoutJS, jQuery, Foundation and SockJS. Lots of other Python libraries were used too, such as bitcoin-python to handle the RPC calls to the coin daemon. Database-wise, it's running off PostgreSQL, using momoko to connect to it from Tornado for async DB calls. Here is one of the sites I have running this code: http://coindice.supercrypt.co.  As I'm no longer actively maintaining those sites, I decided to put this up on Github publicly in case anyone is interested. Have fun :)! Just for information, most of the content still references Aiden dice, which is one of the latest dice sites I've built.
