Guest Book Alternatives

I don't really see us doing a guest book, so I'm trying to come up with some sort of 3D alternative. Two ideas at present:

1. Some sort of chandelier where I provide the beads or strips of paper and people write their well wishes and name on something that I will then turn into a chandelier. Or maybe they can fasten their individual piece to the chandelier at large. Not sure yet, but check out the third image down here and see that turquoise chandelier? Seems like one could make a version of something like that.

I just kind of love the idea of having something that exists in our home from our wedding and the people who witnessed it.

2. Create butterflies out of pretty papers and then glue them onto small rectangles of white paper. People would choose a rectangle and write their name at the bottom- where the Latin name would probably exist if this were a real collection of butterflies. Then They would glue it down into a glass case we'd have laying out.
