夜雨窗Night Rain

用指尖或鼠标擦开窗上的雾，看看外面的街。也可以在雾上写字，水会顺着笔画淌下来。停住不动，玻璃会慢慢暖开；快速一甩，水珠就滑下去。右上角可以听雨声。Wipe the mist off the glass with your finger or pointer to see the street outside, or write on it and watch the water run from your strokes. Rest still and the glass warms clear; flick fast and the drops run down. The button at the top turns on the sound of the rain.
