I can only imagine how many hours it took to cuticle and polish (messy manicurist?) this gem of a puzzle. Super clever. Loved it.

Thank you Michael and Oliver for such a fun and clever puzzle. Loved it!

I've never heard of using the greek letter Tau to represent the ratio of circles circumference to its radius. Is that a thing? (It's always been pi has it not?)

Absolutely brilliant. I can't imagine how much time and effort went into constructing this just so I have something to do on a Sunday. Thank you so much! I don't understand why some people just have to add something negative yet totally useless at the same time. Ignore those ghouls.
