Truth is stranger than fiction. . . . just today my high school students, who are making "yarn paintings," put together a rock-shaped wad of cardboard wrapped with the only purple string available as a gift to me--and they know nothing of this site or the purple string. I held back my surprise, but allowed them to run loose and wreak havoc the rest of the period. They all ended up with purple string looped around various body parts. . . teenagers!! :sim:
