This nifty little product would be great for lawyers keeping track of deadlines. From the company website:

Timestrips® are single-use, disposable, smart-labels, which automatically monitor lapsed time, ranging from under 1 day to 6 months.

Imagine sticking one to every file, phone slip, or letter.  Then you could just look through the piles on your desk to see what’s about to go bad. ;-)
