Hey Jones,
I know you mentioned using flash for this, so my comment may not be helpful (but maybe it will).
First thing, the site you mentioned isn’t using flash. It’s some javascript that’s moving through photos.
Here’s a snippet from the inspector to show this:
<div id="scancube_jzspin" class="4179" style="visibility: visible; display: block; margin-top: -1440px;">

It looks like they’ve executed it pretty cleanly so I’m having difficulty narrowing down exactly what they’re using. However, it seems to be something similar to this: https://www.magictoolbox.com/magic360/
That said, based on a little bit of googling: I’d probably recommend the officially supported WooTheme’s extention: https://www.woothemes.com/products/woocommerce-360-image/
The officially extensions are almost always cleaner code and more reliable for updates.
Side note: Don’t use flash for anything, anywhere. The support for it is all but dead and it can be an awful security risk to many users.
