The limitations of the contest were that it must support current versions of Chrome, Firefox, and IE10pp2, which it does in this launch version. Now that it's working in those browsers, further browser support and better fallbacks are my top priority.

Yes, the fallback is not adequate for a general release tool, so maybe I should have waited before posting it here. But, I thought people might still find it interesting, and I wanted some feedback before submitting it for the contest.

Apologies to those that are being frustrated by these limitations at launch.

I think the tool is cool, but you could have shown an error message and greyed out/disabled the input elements rather than disable the entire site and block the user from reading anything.
