Because the Scratch Team let a scientifically inaccurate #snowfake appear on the front page. Now with adjustable number of axes of symmetry!
No real snowflake has 4 fold symmetry, so I've made the number of axes of symmetry adjustable, with a default correct number of 6. Feel free to make whatever snowfakes you want however. https://www.youtube.com/watch?v=BIiEsIDenTk
