Thank you, but what is this? Just some random shape?

Thanks.

Could be the actual spindle, a detail from yesterday's spinning wheel labeled The Spindle.

Sort of looks like the outer border of a faceless clown. Thank you.

Thank you!

If we're doing Rorschach inkblot tests then I'm with Pazurumasuta.

Thank You.

Yall are wrong: it's a beltbuckle over a zipper. :D.

Robaharrison - Awesome job!! Thanks so much for attempting the challenge! Yes, this is 100% logical, without the use of temps or any assumptions.

However... my previous point still stands. Good attempt, but as a mathematician, "close" just doesn't quite cut it. In a week or so, when I have a bit more time to get back into creating puzzles, I'll give this challenge a go myself. But I'm not hopeful.

For those wondering, I posted the challenge here:

Good attempt, though the numbers on the side aren't palindromic at all, and the top numbers aren't completly symmetrical. Now I'm really curious as to wether that is actually possible. I doubt it, but it would make for a great puzzle...
