Patron: Have you see the monk hidden on the cover of the tax forms?
As Liz Lemon would say, "what the what?" The patron explained, somewhat cryptically, that the negative space between the stars on this year's 1040 instruction booklet cover design seemed to form a monk.
Can you see it? Hover your mouse over the image to see what he was talking about. It's slightly easier to see on a larger animated version on flickr.
I saw it after he pointed it out, but personally, I think it looks more like Darth Vader. The conspiracist in me knows it's not unusual that secret symbols appear in government printing, but they're usually more Masonic than Imperial (but maybe the stars were just to much to resist).
There must be a word for this - hidden pictures formed by positive space shapes. This is sort of like the distorted tessellations in MC Escher's art, but not quite. I looked around but couldn't find a name or description, so I'll keep looking.
In the meantime, if you're interested, here are a few examples of logos employing negative space.
