How about a journal jar with a nice journal and pen? They have printable journal jar slips here (full color with graphics):
I'm doing this for a few of my siblings. I bought some journals at the dollar store (pretty heinous pictures on the front) and plan to decoupage some art paper or something onto the outside, then fill a glass jar with all the slips and add a fun pen. Then you just pull a slip and use it as a beginning for the journal entry.
