What is it?  Looks like a 295x168 TV up very close.  Not sure why your
dimensions are a factor of 32.  Not quite sure what this object is that you
created.  But 295 x 168 x 3 = 148,680 objects.

Looking again, I'm guessing you read each pixel of a photo and divided them
up into R, G, B components, created a cell with 3 atoms in it, each having
an R, G, B atom, based on the pixel values of the photo....?

If that's it, then would it be "cheaper" to first split your photo into 3
gray photos and do the similar process?  (Cheaper on memory?)
