Retired: 3-foot days-of-week

A handsome older gentleman came by our booth last year and said, "Hey, I'm retired.  I don't need to know the time: I need to know what day of the week it is!"

So I made this. Here, the Suns are at noon, the Moons at midnight, the dots are 6 AM and PM. The pointer moves every 5 minutes and shows you, not just the day, but the time of day ... roughly ...

I had one in my living room for 3 months.  Surprisingly helpful!
