(from intro)
I'm sure they could barely contain their shame. The man was a computer scientist before anyone bothered to string those two words together. He was literally a pioneer in the field. Or did you mean to denigrate generally all people who pursue their passion at their own expense?

I think trying to reproduce some of the diagrams with physical blocks would be difficult unless multiple blocks are placed at the same time.
> Can parabolic d-stacks be built incrementally by laying one brick at a time? The answer is no, as the bottom three rows of a parabolic stack form an unbalanced inverted 3-triangle. The inverted 3-triangle remains unbalanced when the first block of the fourth row is laid down. Furthermore, the bottom six rows, on their own, are also not balanced. These, however, are the only obstacles to an incremental row-by-row and block-by-block construction of parabolic stacks and they can be overcome by the modified parabolic stacks shown in Figure 18. We simply omit the lowest block and move the whole stack half a block length to the left. The bricks can now be laid row by row, going in each row from the center outward, alternating between the left and right sides, with the left side, which is over the table, taking precedence. The numbers in Figure 18 indicate the order in which the blocks are laid. Thus, unlike with harmonic stacks, it is possible to construct an arbitrarily large overhang using sufficiently many blocks, without knowing the desired overhang in advance.
Intuitively, it looks like there should be a valid sequence of row widenings that generates the "brick-wall" stacks, though I am not 100% certain. Assuming there is, the next question would be whether asymmetric patterns such as that "oil-lamp" stacks can be generated, or whether in general the optimal pattern can always be generated.
Might be easier to build the entire stack on its side and lift the entire stack using a large flat board. I'm too dumb to figure out if the weight loading from the top blocks during the rotation/lift would balance the forces pulling the ends out. At worse some pressure on the top would be needed.
(I'm not angry, I'm envious.)
If anyone has seen such a thing please do post.
