That this is an awesome side project! I love when stuff like this gets made. I'll definitely be trying this out this weekend! :D
Also, as a side-note / self-plug, I noticed that you wanted to add a Konami code easter egg. I made a small JS plugin a while back to make adding keyboard codes easy. Feel free to check it out and use it in your project if you want :)
