We only get so much time in this life, and yours is running out, friend. That might seem scary, but it doesn't have to be - it can be motivating. Sometimes you just need a reminder that you need to make it count. This tool sets your Google Chrome homepage and any new blank tabs you open to a clock slowly ticking toward your demise.
"Memento mori" was a popular phrase among the stoics. It means "remember that you will die", but it isn't a sad thing. The saying is meant to remind you that you have limited time in this life, so you shouldn't waste it. You should make a concerted effort to accomplish your goals, spend time with the people you truly care about, and do good unto others.
Memento Mori, from @wimgz, is as simple a reminder as they come. It isn't terribly useful in a practical sense. All it does is count down (with the foreboding sound of a ticking clock, if you like), and it doesn't even bother to actually count down the days (because you could be gone in 60 years or tomorrow). But if the constant reminder that your time is ticking away will help you stay motivated, productive and grounded, this is just what you need. Basically, this tool is the more fun, digital equivalent of writing "memento mori" on a sticky note and attaching it to your computer monitor. You can check it out at the links below.
