This brand new chalkboard clock is printed with all sorts of complicated-looking sums, but before you start thinking that you'll have to dig out your old textbook to tell the time, take a closer look. The answer to each mathematical equation relates its position on the clock's face (so, for example, the square root of sixty-four sits where eight should be).
Think the designers deserve a gold star? It's £29.99 from Firebox.
Pretty and clever, yes, but it still leaves me in a cold sweat knowing I never could, and never will be able to do any of those... But hell, nothing like being reminded of your own mathematical inadequacy throughout the day!
