Just set the alarm and when you wake you'll have to perform a quick maths equation before the alarm will turn off. It's an alarm that seems like a good idea before you go to bed but a bad idea when you don't want to get up. That's why the simple equation should be relatively easy to solve but should be sufficient enough to get the brain into gear.

The Twist Alarm Clock will give you a different sum to do every morning. Turn the dials to complete the maths problem and turn off your morning wake-up call. It won't stop till you solve the sum. An example : 5 - 4 + 1 or 8 + 2 = 10.

The Twist Alarm Clock features three movable dials: two for the numbers on the left to complete the sum, and another to choose the function you want (alarm, date, time, "="). On top of the rather cool geometrical shape, the display lights up red if you press the "set" button for long enough
