This was an interesting interactive piece of art I saw with Natalie when we visited the liverpool biennial.
There was a bit of a language barrier with the lady who kindly showed us the way the piece was supposed to work so neither of us quite knew what we were doing. :)
After washing the booklet in the water we were told to keep hold of it as when it dries out a unique piece of art would be revealed.
Unfortunately when the piece had dried the page didn't reveal anything so it's a bit difficult to distinguish whether it worked or not - i'm airing on the side of not. I did however really like the concept behind this piece and thought the artist (who I can't find on the biennial site) was really on to something.
Slight update*
Having just found my biennial map I've discovered the artist who created this piece. Her name is Marnie Slater and the process behind the piece is called 'watermarking.' I now want to go back and actually mark the pages to see the effects! nvm.
