p Most of us gauge the passage of time through the digital displays on our phones, but there's still something intriguing about watching the physical shift of particles in a classic hourglass.
Apple designer Marc Newson collaborated with wristwatch website Hodinkee to introduce a high-end, very expensive hourglass.
The hand-blown Marc Newson Hourglass is more rounded than most hourglass designs.
It takes 10 minutes to drain its contents from one side to the other.
Hodinkee announced the hourglass earlier this week with a fair amount of pomp, noting,"...the Hourglass is a multi-sensory experience that cannot be communicated in words."
And, oh yes, it will cost you $12,000 (£9,260, AU$16,000) to buy one of the 100 hourglasses.
