If you happened upon this without seeing the 'real thing' first, you can view it here without a download.

I just noticed that when you click the "Download" button on the other version it doesn't actually download anything... So, here's a .zip for all your offline needs!
The .zip contains three files, an .swf, .html, and a .js.

So long as the file is not tampered with at all, you are free to use it for anything you wish.
If you upload a copy of this to another website, I only ask for a message stating that you've done so. A link back to my gallery/dA page is always appreciated, but I've included one in the tutorial itself so you shouldn't need to worry about that too much. (Since it sort of goes back to rule #1 of "no tampering".)
---

Once you've unzipped the folder, just double-click the HTML file and it should open up in your default browser without any problems. (You will still need the .swf and .js as well. Make sure you don't delete them)
Naturally, I haven't had a chance to test this on any computer other than my own, so be sure to let me know if there are any problems.

If you would like a standalone .exe version, please feel free to ask!
