I think that Hans Hagen sent me an example for that, written in
ConTeXt MKIV (based on LuaTeX) for that. (I'm not sure if this was
included or not; there was definitely a document for showing
alternatives for OpenType Math, and there was definitely some document
showing different numbers with different features turned on.)

I need to remember where I have those documents, or you can try to ask
the same question on the ConTeXt mailing list (maybe Hans will find
that faster than me).

I assume that you want to inspect the font and that the exact engine
being used to get the job done doesn't matter so much to you?
