I now have a decimal clock with 10 hours and French Republican wall calendar with 10 days a week. Instead 24/7 I can do 10/10!
As you can tell from the position of the hands, it's really a standard clock with a faux decimal face, so the hour hand goes around twice a day and the other hands like usual, but it looks cool. I used a gift card from my secret Santa to get the clock from Cafe Press and bought the calendar from Etsy. You can see more pictures on Twitter.
