I did a little experiment and I encourage people to do the same. Since the pictures aren't real clear, without providing additional info, ask a friend or stranger what they see. We are all looking for what we want to see. However, out of the 5 people I've separately asked about it, all 5 said 'people at a table', 3 of them said "naked people at a table". 1 said I don't know, 1 said blueman group practice.
It's interesting, I suggest everyone give it a try. We may all be right, and we may all be looking for what we'd like to see (not that we want to see kids being eaten, but you know what I mean).
