Thanks for the link! That one is not that old but I also remember it. It is a combination between the sand box concept ( alas Sismik-box) , Flexyrack variation and Finite Element.
The one I talk was a big box filled with sand and weighting over 300lbs. Once you filled it, stays there.....top it with a busher block or granite and you are done with the rack.
The above rack mentioned by Mrmb looks great and should be easy to build too.
