Subject: [PATCH 1/5] I've added a Pygame script for a bouncing ball animation.

This script, `bouncing_ball.py`, creates a simple graphical animation:
- A ball moves and bounces off the edges of the Pygame window.
- Two green triangles representing trees are displayed on either side of the screen.

Features:
- Initializes Pygame and sets up an 800x600 display.
- Defines a `Ball` class to handle position, movement, and drawing of the ball.
- Includes a `draw_tree` function to render simple triangular trees.
- The main game loop updates ball position, handles bouncing off screen edges, draws trees and the ball, and controls the frame rate to 60 FPS.
