This article was posted on my Facebook page this morning. I had to pass it on. Those 'illuminated manuscripts' are cookies. Here's the link: http://boingboing.net/2012/05/24/illuminated-manuscript-cookies.html
Myself, if I'm putting in all this work to create something, I want to be able to look at it for awhile. Unless it's sandcastles. I enjoy watching the waves dissolve the sharp-edged walls of my constructions and carry them away.
What about you? What kinds of ephemeral art would you work hard to make, then enjoy watching disappear?
