When the dimension of all things visual is more important than the story you wanted to tell with your art, you enter the territory of ornaments.
Normally, when you describe something as "deep" that means what you see extends far downward below the surface.
A deep surface is therefore a contradiction in itself...only possible if we turn to philosophy.
If everything turns out fine, the ornament enhances the appearance of something even if what you added is unessential, nevertheless being beautiful in itself.
The Accessory""
art & motion by whornung
All art is at once surface and symbol. Those who go beneath the surface do so at their peril. Those who read the symbol do so at their peril. It is the spectator, and not life, that art really mirrors. Diversity of opinion about a work of art shows that the work is new, complex and vital.Oscar Wilde
When I started interrogating myself about the possibility of ornamantal things having a deep surface, I came quite soon to the point where I stopped thinking about it...it was just too deep for me.
