"Rock Star" digital photo on adhesive paper

This was one of those mistakes that can become something more. This was a photo that was sent to the laser printer and someone left some address labeling sheets in the printer. I peeled them off and spaced them evenly apart. It suddenly became a more interesting picture than the original photo.

I then noticed an optical illusion that the spacing created.

Dark patches appeared in the crossings of the spaces. It is the same effect you can find in the Hermann-grid illusion (see below). The photo is obliviously weaker than the true illusion, yet I can see it. Can you?
