I like the idea of many individual separate 'units' to make a whole. Like how many individuals/characters make a community. I don't know, i'm going off on one a bit. I don't know...like a basic example of the general idea would be to have alot of ribbons...or 'something'? Each person who came to the park would get a 'ribbon' maybe write a message on it...and tie it to something..and the final outcome would be made up of 100's of individual contributions.....like leaving your mark in the park......?? I remember coming across a tree in the woods when I was little with loads of coins hammered into it from 100's of different people who had come across it....it's called a wish tree apparently. But the individual things could be really unusual....(Laura)
