52 Projects from Jeffrey Yamaguchi is delightful. Here's an excerpt from Project #2:

Find a recipe for key lime pie. If you've already got a favorite recipe for key lime pie, even better. Make the pie. Take pictures of the pie. Invite some friends over, and take pictures of them eating the pie. Have a friend take a picture of you eating the pie.

Next, get a box and some limes. Put the limes in the box, along with a handwritten copy of the key lime pie recipe and the pictures that were taken of your key lime pie party. Mail off the box to a friend.
