Flag. (Don't use turbo: this is to be a slow frost growth) Adjust fall speed and transparency. Fractals: snowflake, frost, and winter tree.
Remake of my "Frozen Fractals" with new sliders and effects for this studio. Koch snowflake fractal, and Tree fractal were from my other Scratch programs. Frost by L-system fractal. Fractal is symmetry across scales, large and small. Music is my MIDI version of sugarplum fairy by Tchaikovsky.
