This is an idea I submitted to Thinkgeek (and was since rejected). Basically it was a USB widget that sat on your desk and provided helpful notifications, some which were goofy (coffee levels), others more helpful like telling you to get up and stretch.
It could also alert you to lunchtime or breaktime, when you got an email, or when the internet was out. All functions would be programmed by your desktop computer.
The design was based on the typical dashboard you’d find in your car. If programmed, it could also have chime sounds like a car too.
