Does anyone know if that photo set or video is still available? It was the first thing I found in early UMD days that got me hooked.

I don't know how you would go about getting it. The last I heard the embargo was still in place where Ariel was not allowing any content created by her or commissioned by her, or where she appeared to be sold here. There are a few threads you can read about that whole situation if you want to, it was pretty ugly when she left.
