"Face" Dimensions of Icehouse Pyramids

This was from a discussion that Eeyore (Elliott Evans) and I had on the Icehouse Mailing List. I hung it here because I think it might be useful to someone someday... See this for measurements in 32nds of an inch.

	I'm glad somebody told me this *NOW*.  Not
having any kind of CAD package, I'm going to do some
manual trigonometry:

3-pointers: 1" by 1 3/4"
SQRT(.5^2 + 1.75^2) = 1.82003

2-pointers: 25/32" by 1 3/8"
SQRT((25/64)^2 + 1.375^2) = 1.42941

1 pointers: 9/16" by 1"
SQRT((9/32)^2 + 1) = 1.03880

	Huh, doesn't look like *so* much, now that
I look at it.

	Still, I'm going to post this to
www.oocities.com/TimesSquare/Maze/9346/Icehouse/piecesize.html
(unless one of the patentholders tells me to take it down)
to benefit all of the rest of the Blessed Piecemakers.

	These numbers were generated with (bad) Excel
on (worse) a Pentium, so feel free to check them!

	I suppose the name will have to be "Pieceniks."   ;-D
