Press green flag to start drawing a six pointed snowflake. (press the green flag again to make a new random 6 pointed snowflake) Press the spacebar to draw a eight pointed snowflake. (to make a new 8 point snowflake, press the green flag again then the spacebar) (Shift+green flag for turbo mode)
The bug/glitch in this simulation is when you switch from a 6 pointed snowflake to a 8 pointed snowflake. As you can see, the 8 pointed snowflake is not symmetrical and sometimes draws a horizontal line.
