I thought I downloaded it and viewed the source code, and remember being impressed by it, but now I can't find it. Maybe I just did a right-click -> view-source in the browser rather than saving it to disk. I think it was hosted on d.n so now it's gone. 
Yeah, it was hosted on: https://dice.ninja/static/html/new.html
Unfortunately I didn't make a copy of it either
