Yes, that incredible mandala is created entirely out of colored sand. Not the aforementioned mandala but close enough.
The sand art was left roped off over night with no guards (monks have to sleep sometime) and guess what. Some lady wasn't watching her kid for a minute and he ran all over the sand and created some art of his own.
According to witnesses, the monks didn't seem too distraught about how some little pissant destroyed tens of hours of labor and so they went back to work recreating the mandala. Somewhere in there is a grand metaphor about American culture but thats another story. You can link to some Kansas City local news coverage of what happened here and you can see what happened to the kid after the reporters backs were turned below.
