This is another cop-out feature article. I'm not really writing anything new or astounding. I'm just pointing you to a project I did.
Jeremy over at Blprnt.com has started a collaborative project called "Separations". What happens, is one person creates a design piece, which is then passed on to someone else, who can alter it in any way they choose. There are five "germ lines" that go on like this side by side, with the next "mutation" (participant) being chosen more or less out of a hat from a pool of designer's. I am the third particpant in the first germ line (therefore mine is the second mutation). Curt was the first in my germ line, and Little Lea picked up where I left off [editor's note: Lea is still around somewhere, but her site is long gone.]. Talented people, all.
