One Snow

For the Holiday Season Challenge, I thought of creating some animating (flying) snowflakes. So I started with creating one piece of snow. My idea is that this snow should fall from about 30 meters above ground. It should fall with some acceleration but not to fast because it is light. It should also spin a little while falling. For an easy beginning, I used a scaled rectangle to be the snow. If this works, this snow can be easily transformed into a more beautiful snowflake, and it can be multiplied to create many falling snowflakes.
