Karen just sent me a link to the Hello Kitty USB Hub! From the web site:

Hello Kitty responds to your keyboard motion by talking and moving! Type with Kitty! Keyboard action and sound function. Hello Kitty responds to the keyboard and mouse motion by moving herself! (Moves both arms and head) Hello Kitty will talk with you, along with the input motion of the keyboard. (Kitty is able to talk in both Japanese and English. The languages can be switched.)

I believe you can make Karen burst into apoplectic fits of joy if you buy her this. Just $89.99. :)
