Help with Flash intro htaccess re-direct

Hello!

I’m looking to have a flash intro on an existing wordpress-powered website.

The idea is to have the htaccess file access the Flash animation, embedded on home.html, be seen first, then have the Flash animation call index.php to take us to the main site.

However, I’m not quite sure how to go about this, as every htaccess redirect trick I’ve seen on the web seems to create an infinite loop of the flash animation. Any ideas on how to make this work?
