Implement Dynamic Weather-Based Background

[yunji0387]

Implement a dynamic background that changes its design based on the current weather conditions. Currently, the background consists of a moving cloud against a blue sky.

Here are some ideas for the weather-based changes:

• Wind: When the weather is windy, I'd like to adjust the background's motion speed to simulate the effect of strong winds on the clouds.
• Nighttime: During nighttime hours, I want the background to transition to a night-time color scheme to reflect the darkness of the night sky.
