Seamless

I was studying cracks in the ceiling,
wondering if one could draw them;
draw the ceiling itself -
as it actually looked
I could hold the page at arm's length
above my face
and there would be no difference
Seamless

What would that be worth?

And over by the window
the light changes so subtly
on the ceiling
There is no fine line
showing light from dark
It's a gradation
so delicate
you can not tell light from dark
but if they were fragmented,
placed side by side
How does one render such?

What would it be worth?
