Will keep working on it until I figure it out.

Had to temporarily remove my mockup .. and I have the completed video ready to go, but there's a problem with the music, per YouTube. They say it belongs to a certain artists, who holds the copyright, and Jewel Beat, where I downloaded it, says they own it. I've emailed Jewel Beat, but it's a holiday, so I'm not expecting to hear from them today.
I'm going to try to show it from my website server while this YouTube issue gets resolved. May not work. We'll see...
Heck, I couldn't stand that stopping to buffer... here's a YouTube version with substitute music. It's very, very similar to the tune I originally used. So far no notices from YouTube about this one. Hopefully, I'll hear from Jewel Beat tomorrow and can get this resolved.
