I agree, the Brian Daniel composition is terrific.
Regarding its background, some clarification seems warranted. He has not combined two puzzles. Rather, he has used one principle in two ways, simultaneously. That's a very fine idea, but not without precedent.
The root concept is what Martin Gardner termed "The Principle of Concealed Distribution."
The most popular application is to cause visual information to vanish. Surely the best modern version is Pat Lyons' "The Vanishing Leprechaun" (1968), but that was by no means the earliest. A prior entry, also quite popular in its day, was Sam Loyd's "Get Off the Earth" (1896).
But there is another widespread application, using the same principle to apparently cause a physical vanish of a portion of the item. This goes back at least as far as the Italian architect Sebastiano Serlio, who published it in 1551.
A number of well known magicians and puzzlists have devised versions of one effect or the other, including the aforementioned Martin Gardner, Theodore DeLand (Hi, Richard), Winston Freer and Mark Setteducati. Others have come up with astonishing new effects
using the principle, notably Paul Curry, Mel Stover and Masao Atsukawa.
As for the idea of devising a layout that accomplishes both of the basic effects (i.e., an informational vanish plus a physical vanish), it has been done before. If you go to here
you can find one by Gianni A. Sarcone. There have been others.
This is to take nothing away from Mr. Brian; simply to provide additional information.
