On the blog of a Roman Cortes, he's done something really impressive - created an image of Homer Simpson using only CSS to style HTML elements - no images involved! Now that's pretty amazing. It just goes to show what CSS can do. He's reported it as working in:

• Internet Explorer 5.5, 6 and 7
• Opera 9
• Firefox 2
• Safari 3

To get it working in such a range is what really impresses me.
