LED Hourglass

If you need to measure a specific amount of time but don't want the soothing, pleasant steady flow of sand from one glass chamber into another, or you're an android who loves all things electronic, perhaps you want this LED Hourglass. The advantages it has over a traditional hourglass are 1) you can specify exactly how long it runs (up to an hour), and 2) it beeps and flashes when it's done, so you don't miss it. $19.99 USD.
