Monday Brain Teaser

"MOMANON"

. "Decode" the above word ... or acronym ... or anagram ... or whatever it is. Anyone who is in Mensa (and I am not. Don't get me started on Mensa) should get this in a matter of seconds. Wikipedia won't help you, but googling will. . Or you can find the answer in the Comments to this post. Oh yeah, the image has absolutely nothing to do with the Brain Teaser. It's just neat to see Legos used in an illusion.
