Ah! I gotcha. The cyan is just the background and the white/grey are
graph bars. That makes sense now. Thanks. You've probably seen the
black and white image (no greys) that's either a side giew of a goblet
*or* two faces in profile, almost nose to nose. I was viewing each line
"the other way" -- with the cyan portion being the object (the graph bar)
instead of the background. Like the goblet/faces image, once you see
both, you can easily flip your perception back and forth between the two.
