An interesting interview question

[garote]

This morning in the shower I came up with this question for interviewing a web developer: "How many ways can you come up with, to draw a circle in a web browser?"

Here's my list:

1. Declare a canvas element and draw a circle on it using JavaScript.
2. Construct one artificially in HTML from scaled table segments.
3. Use inline SVG code to describe a circle inside a div.
4. Embed an object - Java, Flash, video, etc - and draw a circle using that.
5. Print a unicode character of a circle, really really large.
6. Reference an image of a circle, in HTML or in an associated stylesheet.

Any I missed?
