Alleviate "Computer" Wrist Pain

I keep a timer at my desk and set it to go off every fifteen minutes. Then I spend a minute loosely "flicking" my wrists up and down and side to side. Then I "roll" them around, reversing direction. Since I also suffer from pain in my shoulder from too much "mousing", I will roll my shoulders forward and then backward. It really alleviates the tension. If I have 10 minutes or more, I go through a whole series of yoga type exercises that really make me feel good and rejuvenated.
