"A bleedin' pile of bricks - I could'v done that"
This springs to mind, reading the posts subsequent to the OP.
This sort of stuff exists within a defined situation ie: a 'Gallery'.
In everyday life, I find a stack of bricks interesting, a wall, a collection of pebbles, maybe a collection of bicycle wheels - whatever. What gives this stuff an 'edge' is the location + the intent of the artist.
Fnaar's pineapple falls into this category and the hypothesis is that a gallery will 'install' pineapple cubes. Do you want to engage? Your choice to wade through said cubes as a piece of 'self-performance art' (You will be videoed doing it - of course!) and suffer the pleasure of ham fisting at the end!?
Anyway. It all seems so abstract but.
If you go somewhere - let's say a revered institution like the National Portrait Gallery, pop upstairs to check out Nelson:
Ignore the fact that it looks like a person, clothed and with metallic buttons etc everywhere - just go up close and see the paint applied to a bit of canvas. It looks like a load of old squiggles - something you wouldn't even bother looking at if it was 'in your face' as er - a load of squiggles.
When I look at these squiggles in close-up, I'm trying to turn them back into a button or a gold braid epaulette. It's bloody difficult, but I would rather imagine than have a bit of pig stuffed down my trousers. (Except if it was by a chosen few here on CC

).
So, it's all about the stimulation - at first sight, on closer inspection, and lasting impression.
But you got to get your pineapple chunks into the exhibiton arena first, and then be prepared to back it up!
