In this case, I don't think it is.  Pascal's triangle is used for distributions,
etc.  It's not a geometrial form, really.  This is a 3D version of what is
called a Sierpinski Triangle.  The "cheese" looks like a Sierpinski Box, but it
doesn't have enough holes; it would have to have 9 holes per side at level 2.
Oh, well..
