An Illusion

Above is a picture. Below is the same picture. Your task is to explain how that can be so.

Is This Puzzle Wrong?

"8, ?, 4, ? 1, ?, 6, ?, 2

Add some odd numbers to make the odd sequence logical (pun intended)."

This an apparently simple number sequence puzzle familiar to you from IQ tests.

I, so far, find it difficult. It may be that there is an ambiguity that needs to be resolved (see my posts on the the title link) or it may be that I am simply stupid.

You decide.
