For CSI-loving couples, consider creating a thumbprint collage guestbook.
Have ink blotting pads in different colours next to a framed image (and lots of wet wipes nearby!) and have guests create a fingerprint masterpiece! Ink pads are available from Peachwik via Etsy.com but you can easily create your own or check out Walmart or Staples.
If it is a large enough canvas, consider allowing them to sign their names overtop of their print (or initials) too!

You can find the basic prints (ie, bare trees awaiting the thumbprint leaves, etc.) from Peachwik.com
