This might seem silly, and if there is no good and practical solution... I will live.

I am a programmer and sit at a computer 10 hours a day - and even though the rest of me is nice and warm (at least warm), my fingers are cold as ice.

Are there some gadgets or tricks to keep your fingers warm while typing/mousing? Gloves do not seem like a good solution, since it hinders the movement of the fingers.

I have sometimes put my extra laptop next to the mouse pad, so that it vents hot air on the mouse - and that works... But it is not very practical, plus it only works for one hand (and not very well).

Tips?
