Present Perfect

I want to make a series of sculptures based on works of art that other people tell me about having seen, but that I've never seen myself. This one is based on a piece Mike Fleming saw in the MoMA a few years ago. He said a marble-sized metal sphere was placed on a keyboard's letter G so that the computer was continuously typing GGGGG... and that you could see it had been typing G for a long time based on the page # displayed in Microsoft Word. He can't remember the name of the original artist.

So, I placed a large rock on my old laptop's keyboard so that it types the letter Y continuously and infinitely.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

I think that if I ever show this in an exhibition I will use a rock that I find in that local area. When the exhibition is over, I will print out the document (however many pages, depending on the length of the show) and then display the stacked pages with the rock on top, as an artifact. Each exhibition at all the different locations will then produce its own unique artifact.
