Well thanks to a post from before I was on the list (thanks ee0r) [http://lists.looneylabs.com/pipermail/icehouse/2006-April/000565.html] I was able to determine that the minimum amount of cardboard you need to cut out a 3-point giant pyramid (using his mentioned 8x scale) is a rectangle measuring 1' 7-3/8" by 1' 6-5/16" (without glue-flaps) Alas these boxes I have so many of are too small for such an endeavor (though I suppose I could see if I could cut two half pyramids and glue them together, rather than having only one glue point... I have an excessive amount (several hundred) of 15"x14"x8" boxes that are just going to be shipped to the recycle dump... so I thought they could be made into pyramids... (back to AutoCAD to try and see if I can fit the shapes onto the box.) PS: Momma rabbit, how are the giant pyramids coming along? -Evan
