Total frustration combined with a functional desk light - who would have thought? You can twist and turn this light the same way you did the original, maddening Rubik's cube. You'll get two hours of play once it's completely charged. When you're not using it, just mount it on its base and use the included USB cable to charge it. It measures 12x12x12 cm, so it's big enough to give a fair bit of light while not using up a huge footprint on your desk. If you expect to get any work done, though, you'd better put it in a drawer - it's addictive!
