    if length < 2: return
    turtle.up()
    turtle.goto(x,y)
    turtle.down()
    turtle.seth(direction)
    turtle.pensize(length/50)
    if length > 20: turtle.color('saddle brown')
    else: turtle.color('green')
    turtle.fd(length)
    px,py = turtle.xcor(), turtle.ycor()
    slanted_tree(px,py,length*0.7,direction-30)
    slanted_tree(px,py,length*0.7,direction+60)
