Create an animated weather system. It can be literal or absurd, but should include multiple elements moving as part of a greater whole. Animate simple shapes so that they give the impression of natural phenomena. Use colors to hint at emotional qualities. The weather should have an interactive element, reacting to user input.

Examples: Snow and rain. Leaves falling. Wind blowing. Dust storms. Tornadoes. Sunshine. Waves at sea.

Deadline: Presentation Monday at 10.00.
