We’ve featured a number of weird and wonderful clocks here on geeky gadgets but the Pop Quiz clock is in a league of its own. The numerals around the clock face have been replaced with mathematical formulas.
The face of the clock is 30cm in diameter and has a mathematical graph paper print on it and would be the perfect gift for maths lovers and geeky friends. Thankfully the answers should come to me in a minute or two even without completing the formulas.
The Pop Quiz Clock is available to purchase for around $40 from gadgets.dk
