以下是用Python turtle模块模拟梵高《星夜》的动画程序，包含动态笔触效果和色彩还原：

import turtle
import random
import math

# 初始化画布
screen = turtle.Screen()
screen.setup(1200, 800)
screen.bgcolor("#08192D")  # 深蓝色背景
screen.title("Starry Night - Van Gogh Style")
turtle.tracer(0, 0)  # 关闭自动刷新

# 创建自定义画笔类
class VanGoghPen(turtle.Turtle):
    def __init__(self):
        super().__init__()
        self.hideturtle()
        self.pensize(2)
        self.speed(0)

        for _ in range(8):
