I forget the details - it was a couple of years ago - but the idea was that every time you sign something, you modify your key in some random way, resulting in signatures that are still verifiably yours, but also contain the new random modification. Beyond that, I don't recall how it worked - it was quite clever... ah, here it is: http://eprint.iacr.org/2005/147.pdf
Spoke too quickly - that paper is something else entirely. I still can't locate the one I was thinking of.
