For me, it would depend upon how aesthetically pleasing the work of art were.
I don’t find it inherently creepy.
The brooch pictured in that link from upthread was really lovely.
But then I’m the type of person who found it fascinating that there are people and companies who offer to freeze dry your deceased pet, posed in a way that was natural and typical for them based upon photos you provide to them.
I saw a segment about it on some news show and found it intriguing.
At the time I had a calico cat with one of the most unique and gorgeously patterned coats. Everyone who saw her commented upon how beautiful it was.
Unfortunately, this is a really really really expensive thing to do. But if I were richer, I definitely would have kept that guy’s phone number handy for the next ten years or so for whenever she passed away.
But a goodly number of people found the whole idea really creepy.
Everybody’s different.
