jsFiddle is a great online web editor with awesome sharing functionality and collaboration for code snippets.

Try it at http://jsfiddle.net as using it shows it off the most..

My first ‘fiddle’ (http://jsfiddle.net/4mJQ6/) is a CSS3 webkit-only implementation of the marquee tag (as the official module lacks implementation). I do not condone the use of the <marquee> tag.
