Once this starts go full screen. Let it run for at least 20 minutes. You don’t have to watch it the whole time.

```
from turtle import *
from random import randint
speed(0)
def wander():
while True:
lt(randint(5, 350))
fd(randint(5, 60))
if xcor()>=230: # coordinate of x
lt(170)
fd(50)
if xcor()<=-230:
lt(170)
fd(50)
if ycor()>=200:
lt(170)
fd(50)
if ycor()<=-200:
lt(170)
fd(50)
wander()
```
