Are you feeling the urge to color on your own walls? I’m sure it would send your kids into shock if you did. Well then this everlab’s 1 Hour Circle might be the clock for you.
Place a writing utensil in the arm and it will make a circle on your wall. It takes it a full hour to create the circle; the arm goes around just like any other clock would. It just colors on your wall in the process.
If you want to you can put a piece of paper on the wall so that it colors on that instead. The clock comes in yellow, pink, blue, and green. To vandalize your own property it will cost you a mere $21.
