also today i very briefly played around with the tracings. i got some fishing line and some wire. the wire could be interesting, and even the fishing line too. but it is something that needs to be tested with all of them, or quite a few at least to get a better sense of how it works. i actually think the presentation of them using just the pins is very effective. when they are pulled slightly away from the wall they cast shadows on to the wall behind them. i shall have to sort it out on monday for the exhibition that goes along with our presentations, which are on wednesday.
