I'm sure I'm being dim, but is it possible to view the rendered output of a gist?
This is the gist I'm interested in: https://gist.github.com/844752/420cc52eb4910fe8fa2bec9e13daab18b6230503
Where can I see how it actually renders?
As far as I know gist doesn't provide an execution environment, but you could easily paste this in jsfiddle.
