Simple recursion in Turtle Art. Recursive loop is handled in stack1, with final case of drawing a line. Stack two is used to orient the turtle between line segments. The control variable box1 is used to store total draw length (300 horizontal pixels in this case), multiplied by 4 to offset the division on the first draw in stack2. box2 is used to control recursion depth. Here it's set to 4, meaning we will subdivide the line 4 times.
The division and multiplication in stack2 is based on the number of stack1 calls. You need to divide by one per call, then later unwind by one per call. Since the snowflake is composed of 4 stack1 segments, the divisor/multiplicand is also 4.
