[cfm] Sorry you feel the need to apologise - there was nothing wrong with your choice really.
Something I've said before on more than one occasion ... I think it helps to reply to a question without changing the questioner's original wordage. Spinning a question forces a 'double read' which can get tiresome. It can also mislead, eg. your reply to CdM's key question regarding a specific profession didn't inspire a rigorous follow-up and perhaps should have?

[cfm] I've only been in the chair once. It can be quite difficult to respond to questions in a manner relative. Some people are quite adept at it. I wasn't. Don't dwell on it, regardless of the somewhat snide comments you might receive.

[cfm] Don't worry about it. I've made the same mistakes before, we all have.

To hurry things along I will pick up this discarded baton and offer an ABSTRACT with MINERAL & ANIMAL connections.

[cfm] Work of art? I would say Yes, but not everyone would agree.

[cfm] A thing, not a type of thing? Yes.
[Software] After 1900? Yes.

[cfm] Visual Art? I said before, not everyone would agree it was even art. That said, if it is art, it probably qualifies as visual art. (I am guided solely by Wikipedia in this matter, however).

[Rosie] A style? No.
[Dujon] Monumental? No. *Audience Mirth*
[cfm] Metalic? No.

[cfm] Intended as art? No, at least I doubt its creator(s) would have used that word at the time.

[cfm] Metallic association? No.

[Phil] man-made? Yes.
[Chalky] name of a place? *Audience Applaudes* Part of the AOTC is the name of a place.

[Chalky] Wet Stuff? No.
[Phil] Can you see it in a specific place? Yes, I have seen it in several specific places.

[cfm] Could it fit inside a microwave oven? Yes, it's an abstract.
[Chalky] Is it really an Abstract? Yes.

To clarify the point, the contents/title of a book, film or TV programme would all be examples of abstracts that can be seen. (I'm not saying it's one of those but they still exist).

[cfm] Film or TV? No.

[Chalky] logo? No.
[Rosie] A kind of magic? No.

[Chalky] Musical connection? Yes, music is involved to soem extent.
[Software] It's only a model? No.

Typical example of my stupidity - Software asks "Camelot?"
The reply comes back " It's only a model - No "
Result: I spend more time worrying about my failure to make a connection between these two posts than I do about the actual resolution of this puzzle. Thus confirming why I shouldn't be playing this game.

[Chalky] A Play? No.
Sorry, I've been preoccupied, my redundancy notice came through on Friday.
