Homework 5

Create either an HTML5/SVG page, a HTML5 page that includes SVG, or a pure SVG page that includes some animation:

• The page should include at least 2 animations
• The animation should be useful in one way or another. You can explain the purpose of the animation either within the page or by other means (e.g. through a comment in the world classroom)
• Bonus: Some interactivity (e.g. a mouse click or mouse over)

You either can create your own drawing using any SVG tool or add animation to a clipart file from http://openclipart.org. If you use external resources, please cite, e.g. in the SVG code using the desc element.
