Grid art made of black squares is the best kind. It stands out so well, unlike pictures formed by circled letters or connect-the-dots. I immediately take notice when a crazy-looking grid like this breaks the monotony of the normal grids we see every day.

Great aha effect on the TOP HAT, too. I had other ideas on how SCROOGE MCDUCK and WILLY WONKA might be related (rich cartoon characters, perhaps?), and even after ABRAHAM LINCOLN, I didn't see their commonality. Beards? Can ducks have beards?
I'm often not a fan of interlocking themers since this causes all sorts of filling problems, but there was something elegant about Ross's layout today. After some study, I realized it wasn't just that Ross wanted to show off. He had to use this interlock!
Why? With mirror symmetry, a long, unpaired answer can run horizontally. No problem … except when you then need to work in a pair of entries longer than seven letters. Those need to go vertically, and that creates a problem because of the long horizontal answer.
Why?
WHY SO MANY QUESTIONS!
Fine, try to lay out WILLY WONKA and ABE LINCOLN horizontally, using in this mirror symmetry arrangement. I'll wait.
See? Can't do it, can you? Mirror symmetry is great for certain theme sets, but it sure makes others tricky.
It's so fortuitous that Crucivera shined her glory upon Ross today, allowing for such beautiful interlock. More often than not, there is gnashing of teeth and promises of animal sacrifices if she would just cooperate.
As I mentioned above, filling around interlocked themers is tough. See: the AGT / OMN region. It's a fine product overall, though, a testament to Ross's skills.
Me and my long memory immediately flashed to Liz Gorski's FROSTY masterwork after solving this puzzle. Hers headlined the TOP HAT, which made it stand out so impressively. Still, I like that Ross gave me a fun aha by making me think about what connected these four individuals.
