Makes select boxes look nicer. Gracefully degrades (maybe, I didn't try).
There is no demo.
There are no options.
You can use this plugin for whatever purpose. T .css includes a link to the image used, you should read its license and change the image if you don't agree with it.
Include jQuery (tested with 1.6.1), include the purdySelect stylesheet, include the jquery.purdySelect file and call $('select').purdySelect();
