Dave is here, we're having fun.  Try <a href="http://validator.w3.org/check?uri=http://www.ugcs.caltech.edu/~takoyaki/index.html">validating my html</a>, or <a href="http://jigsaw.w3.org/css-validator/validator?uri=http://www.ugcs.caltech.edu/~takoyaki/css/index.css">validating my css</a>.  Another stylesheet, number 5.  I'm thinking of switching my pages to php.
