What electronic products can improve the quality of life?

There is an electronic product, the weather cube, which redefines the weather forecast. The weather cube is equivalent to a small water tank, which displays the current temperature electronically. Interestingly, it can visually display the weather: the water surface is calm, which means sunny, and the glass is covered with water droplets, which means rain. Waves represent wind and steam represents fog, which is too classy.
