It took thousands of years, but we finally have a digital sundial - ScienceAlert

'... Created by a French engineer who goes by the name of Mojoptix, the outdoor clock uses a number of carefully calibrated holes in the triangular part of the sundial - officially known as a gnomom - to make sure the right time is projected on the plate below.

So, when it's 10am, you'll see 10:00am projected onto the shadow below.

There are some limitations to the design - it obviously doesn't work at night, and is only designed to be accurate between the hours of 10am and 4pm.

And it only tells the time in 20-minute intervals, so it's probably not going to help you get to your next meeting on time.

But it does all of this using nothing but beams of sunlight - the same thing our ancestors from 3,600 years ago used to tell the time of day with, so it's a pretty cool upgrade.
