She Just Couldn't Resist...

Jonathan Jones at The Guardian writes about the woman who kissed the Cy Twombly painting.

I remember one night at 2 or 3 a.m., after a week of all-nighters, I had an uncontrollable urge to lick the painting that I was working on: it was one of those sleep-deprived moments when I could not believe that I was looking at something that I had actually made.

I am not normally one to be starstruck, but I can remember over the years having the strong urge to touch the work of various artists I admire, thinking there would be some sort of mystical transfer of creative energy.... and I think I might have given in to those urges once or twice.
But I never left marks.
