Very slick, clean, and well done! What is the stack you're running on/how are you storing the data?

I'm happy that you like it. Data: in browser and backend. The stack is custom - based on canvas famo.us and node on the server side. Is there anything else that might be of interest to you?

Love this. Great work!
