2. The ice is falling, and the snowflake is flying in various postures in the air, or flying, or hovering, or falling straight and quickly and laying on the ground.
3. In the morning, open the curtains and look at the glass window. It is covered with glittering window grilles, some like lush coconut groves in the south, some like towering cypresses in the north, some like budding roses, and some like blooming peonies. It's really beautiful and colorful.
4. Spread all the ice grilles, a firecracker is a dream, and it is a mirage outside the curtain.
5, ice window flowers fall into the window white edelweiss, and thousands of trees are born. A piece of ice heart weaves dreams together, and I look forward to Mu Xiachun in the cold night.

Pattern rule
The condensation of water vapor or water droplets on the window will obey the fractal model in mathematics. That is, the small snowflake model is about hexagonal. Look carefully, many complicated and unique window grilles are also composed of small snowflakes or hexagonal scales. It is also for this reason that it is easy to form three-dimensional and touchable patterns. The snowflake shape below is a model for this reason.
Wind and gravity. During condensation, there may be a slight cold wind blowing in the gap near the window (which is very important for the formation of window grilles), which may make condensation and melting form a dynamic and balanced process, produce subtle ice water flow, and finally form landscape paintings or other forms of ice grids. In particular, some window grilles have no patterns or monotonous patterns on both sides. There is a kind of ice window grilles that are not very beautiful, that is, the two sides are horizontal, the middle is blurred, and the top and bottom are vertical. In fact, this is the best expression of this truth.
The properties of glass itself, especially the surface morphology. The surface condition (flatness or stain) of the glass will directly affect the accumulation process and shape of the small snowflakes, the infiltration and flow of wind, and also determine the flow of the tiny ice water, so it can affect the shape formation of ice window grilles. Like all kinds of strange ferns, it is a realistic portrayal of this paragraph. The above three forms make it form ice window grilles with different shapes.
