Yep, no joke, some infinitely complex shapes can be made with NBs of various arrangements and types. Only one really works so far that I found, and that is the Cantor ternary set that you see right here. It is built by removing the middle third of a line segment and then repeating the process with the remaining shorter segments. It can also be done with NBs, as each layer is triple the length of the one below it. In this case Eighty-One is shown as a very wide rectangle, with 2 Twenty-Sevens under him. Then are 4 Nines below them, followed by 8 Threes and finally 16 Ones. I've also found out the total of all of these NBs is 211, which is also a power of 2 less than a power of 3. Other members of this sequence include 65, 19 and 5 (I guess I'll call this Cantor Club). I've also heard a Sierpinski carpet and Menger Sponge can be made from just NBs, and possibly others.
