These presentations are basically riffs on the standard version of this routine, as demonstrated my
Michael Ammar at the beginning of the DVD. The effect has since undergone a major advance, in Weber
and Dill’s A New World, far superior to the standard version. Trouble is, it’s no longer available.
I was fortunate to have just acquired that one from an estate sale. Grab it up if you can find it.
But you could do far worse than the DVD under review here.
