If you’re a Mac user, and you find yourself working too hard at the computer (typing and staring at the screen for hours with no break), give Time Out a try.

This hand freeware app will allow you to schedule regular breaks throughout the day where it actually locks your screen and plays music from iTunes (if you so desire). Currently, I have it set for a 15 second break every 30 minutes and a 10 minute break every hour. I leave the iTunes integration off so that I’m reminded to actually get out of my chair and away from the computer.

If you’re a fan of Apple’s latest toy, Time Out is also available through the Mac App Store.
