Online Break-Timer
I have written an online break reminder. Basically it will bug you to take a break from the computer every 30 minutes (you can configure the time interval).
If you're not ready to take a break yet, you can snooze for 5 minutes (again, you can configure this time interval), after which it will bug you again. Leave the computer, rest your eyes, and when you come back, hit the big Restart button -- this will reset the clock back to 30 minutes.
