For kids...or adults! I may do this...
The thought is to have an "I Spy" list of photos guests should try to capture. I'm thinking either to have disposable cameras for guests to use, or have them use their own and then upload to a website after the wedding.
Maybe even have some kind of prize be offered for the best photos picked by the bride and groom and the winner gets a prize or something mailed to them after the wedding.
A fun way to capture some different perspectives of the wedding...and aren't the cards just cute!
