I just added 2 needed lines and reposted above.

I added mouse wheel support so you can spin it both ways and speed it up and slow it down.

I just spiffed it up by using the exact radians needed to make each one exactly even with each other rather than guessing like I was before. I like to Google "radians photos" to get a good chart to look at.
