Project 3: Little Desktop Helper Application

There are a few little apps like this around, but I want to make this one something special. you can choose, or even create your own little desktop helper. She/He will remind you of important dates and times as well as help you keep track of notes and other such things. She can walk around your desktop and play with your icons.
I would like to make her/him almost like a tamagatchi where she/he can be fed, bathed, and played with.

Have a website for other LiDeHe's with forums and maybe a game/point system

Let other LiDeHe's visit other desktops? (might have security issues)

Let other LiDeHe's 'socialize' with eachother after upload to the website. (could be facebook app?)
