Guest Book Alternatives

I don't have much to say... I noticed these two posts and it got me thinking: what are the best alternatives to traditional guest books? Personally, I like the idea of putting my engagement photos into a bound album and having them sign it. I also like the idea of a photo booth with polaroids that the guests can sign and add to a wishing tree...
