Google Mapspelling
This is the silliest form of internet fun, but at GeoGreeting you can use "letters" found via Google Maps to write stuff such as the name of your blog or a note to your wife.
(This is my second straight Google Maps post. And I just finished a half hour with Google Reader, their RSS application. And I have my home and work Firefoxes set up to open on my personalized Google homepage. And I use Google Notifier to alert me to events on my Google Calendar. At least I don't have a gmail account. That would be too much.)
