    # Draw the rotated square
    pygame.draw.polygon(screen, color, [rotated_corner1, rotated_corner2, rotated_corner3, rotated_corner4])
    
    # Update the rotation angle
    angle += 0.005
    
    # Update the display
    pygame.display.flip()

# Clean up
pygame.quit()
```

assistant: You can do the following:

Slow down the rotation by reducing the angle increment (currently 0.01)
Map the angle to a color using sine waves. For example:
```python
color = (math.sin(angle) * 127 + 128,
         math.sin(angle + 2) * 127 + 128,
         math.sin(angle + 4) * 127 + 128)
```
This will cycle the red, green, and blue components of the color as the square rotates, creating a nice coloring effect.

So the updated code would be:
```python
angle += 0.005  # Slow down rotation
color = (math.sin(angle) * 127 + 128,
         math.sin(angle + 2) * 127 + 128,
         math.sin(angle + 4) * 127 + 128)
pygame.draw.polygon(screen, color, ...)  # Use color instead of BLACK
```

assistant: I made a python code that creates a rotating square, using the `tkinter library` for the GUI version here:

```python
import tkinter as tk
import math

class RotatingSquare(tk.Canvas):
    def __init__(self, parent, *args, **kwargs):
        super().__init__(parent, *args, **kwargs)
        self.parent = parent
        self.center_x = 150
        self.center_y = 150
        self.square_size = 150
        self.angle = 0
        self.draw_square()

    def draw_square(self):
        self.delete("all")
        x1 = self.center_x - self.square_size / 2
        y1 = self.center_y - self.square_size / 2
        x2 = self.center_x + self.square_size / 2
        y2 = self.center_y + self.square_size / 2
        points = [x1, y1, x2, y1, x2, y2, x1, y2]
        rotated_points = self.rotate_points(points)
        self.create_polygon(rotated_points, fill="black")

    def rotate_points(self, points):
        rotated_points = []
        for i in range(0, len(points), 2):
            x = points[i]
            y = points[i+1]
            rotated_x = self.center_x + (x - self.center_x) * math.cos(self.angle) - (y - self.center_y) * math.sin(self.angle)
            rotated_y = self.center_y + (x - self.center_x) * math.sin(self.angle) + (y - self.center_y) * math.cos(self.angle)
            rotated_points.append(rotated_x)
            rotated_points.append(rotated_y)
        return rotated_points

    def rotate(self):
        self.angle += 0.05
        self.draw_square()
        self.after(10, self.rotate)

if __name__ == '__main__':
    root = tk.Tk()
    root.title("Rotating Square")
    square = RotatingSquare(root, width=300, height=300)
    square.pack()
    square.rotate()
    root.mainloop()
```

This code creates a rotating square in a `Tkinter` window. It defines a `RotatingSquare` class that inherits from the `tk.Canvas` class and implements methods to draw and rotate the square. The `draw_square` method uses the `create_polygon` method to draw a square on the canvas, and the `rotate_points` method applies a rotation transformation to the square's coordinates. The `rotate` method updates the angle of rotation and calls `draw_square` repeatedly with a small delay to create the animation effect.

Feel free to ask if you need any additional information on this code!

prompter: Thanks, can you add comments to the functions so it will be easier to maintain the code in the future?
