I'm a fan of structure that works and this is an example of a three-point support structure that I have come to believe in. (Living in our house with its uneven floors of wood and brick would make anyone quickly embrace three-point designs!) This particular example is a very fluid, contemporary version, but it would be easy to duplicate in more or less extreme styling. It would be hard to pull off in motifs that depend upon that "four point symmetry", however. Aside from the practical aspects of this base design, it works with just about any shape of top, especially irregular ones and feels "grounded" no matter how simple or extreme. IMHO, of course!
The Noguci sample also uses symmetry between the "two" members that make up the three-point base. This is a design that can also be repeatable in a room to tie together a number of objects in the right setting.
Here is an example of using a three point base by Nakashima; slightly different in that all three points are not connected and not symmetrical. It still looks stable, but unlike the Noguci table, this one also visually feels like it's moving...your eye is drawn from one point to another by the shape and the base structure.
There have been other examples of Nakashima's slab tables that also used the three point base...and I plan a version for our great room out of a nice big "platter" of cherry I have out in the shop. And yes, it will have a three-point base.
