Source Code:

import turtle

screen = turtle.Screen()
screen.setup(500,800)
screen.tracer(0,0)
screen.title('Wundt Illusion - PythonTurtle.Academy')
turtle.hideturtle()
turtle.speed(0)

def wundt():
    turtle.color('blue')
    for y in range(-380,400,40):
        turtle.up()
        turtle.goto(0,y)
        turtle.down()
        turtle.goto(-100,0)
        turtle.up()
        turtle.goto(0,y)
        turtle.down()
        turtle.goto(100,0)
       
    turtle.color('red')
    turtle.pensize(5)
    turtle.up()
    turtle.goto(-50,-350)
    turtle.seth(90)
    turtle.down()
    turtle.fd(700)
    turtle.up()
    turtle.goto(50,-350)
    turtle.seth(90)
    turtle.down()
    turtle.fd(700)
    
wundt()
screen.update()

Similar to Cafe Wall illusion, the red lines are actually parallel. Read more about this illusion here.
