Here’s the Solutions grid
The Oracle’s NINA is colored in Yellow and it runs across the top and the bottom rows (so that you can’t say you can’t see it)
The Oracle’s so-called “Autograph” is in the middle in Red. Its an Ambigram (reads the same even if you turn the puzzle upside down)
The Oracle’s Self-portrait is in Blue and the two “O”s (glasses) connect the Autograph with the Self-portrait. The self-potrait also can be seen even when the grid is turned upside down.
In addition to the NINA. the second special feature is that the grid is a Pangram (using all letters of the alphabet in the solutions)
