Stuck on the snowflake portion of Snowflakes in the Ice. The first rotation works fine, but I can’t get it to do the rest of the rotations. My code is

```
def flake(start, end):
# To create a hexagonal flake we need to create 6 line fractals rotated by 60 degrees each time.
side = Vector.subtract(end, start)
a = start
b = end
for i in range(6):
line(a, b)
# To get the next edge, we need to rotate the side 60 degrees.
rotation = Vector.rotate(side, degreesToRadians(60))
# Now need to reset a and b with the beginning and end points for the new side.
a = b
b = Vector.add(rotation, a)`
```

Obviously I have to use the i variable somewhere, but for the life of me I cannot figure out how or where. I know correct code isn’t given out on the forums, but can someone give me a hint?
