Is it a calendar? Yes. Is it a game? Yes. Is it the perfect way to put off work for a few more minutes? Yes. This perpetual calendar by Brass Monkey is as challenging as Steve in finance...but way more entertaining. Start each day moving this puzzle around to get the stainless steel balls inside to land on that day's date, month, and day of the week. It's literally a new game every day.
