I'm an artist, painter and a model designer/builder.
When I put out something for the public, I can be be extremely picky and controlling when it comes to where and how you see my stuff.
I agree with OldMan that the artist must retain control over how their work is presented.
But in reference to Barley's original comment, I was once at a scale model event and there was a builder there who had created some sort of diorama that I did not get the chance to view properly.
On the table he had a large 'box' made up of various panels. It wasn't all smooth sides, but it was unfinished and unattractive looking.
Thinking back I'm going to guess it might have been 2 to 3 foot square and at leat half that tall, so it took up plenty of table space.
On one side was a small window, much smaller than a trading card, forcing any viewer to stoop and look into the box by a very specific angle.
Obviously the box contained a diorama that needed to be viewed only from a specific perspective.
I assume there was lighting in the box too.
All I can say is the reception was less than enthusiastic, with most spectators passing all together or reluctantly bending down and giving up fairly quickly.
While I may support an artist's desire to control how their work is viewed, there must be a tolerance/acceptance of the viewer's willingness to accommodate the presentation.
In this case, designing a diorama that can only be viewed from such a specific and controlled position might not have been a good idea.
If you make something too difficult for the viewer to take part or understand, they will not show any interest.
