Holy moly! That's incredibly super-tastic!
And just a 2 person final project!? Yowzers!

Very nicely done.

By the way about the paper, I don't known what it was you signed for the ACM, but I've never heard of them going after someone for distributing copies of their own paper on the web. But if you're worried, frequently people take a slightly modified version, perhaps the original submission before final edits, and put it up as a "Preprint".
