Spectre

A "Spectre" is a new shape. Yes, I did say new shape ! It is pretty incredible that there can be any such things as new shape , I mean, how do we not know all the shapes already? Also, to be fair, it is a reasonable bet that the ancient Greek's knew of this and forgot to write anything down. But certainly in my life time - this is indeed a new shape . Discovered in 2023! So what makes it special?…
