Change the mouse pointer using JavaScript
Javascript is pretty good at manipulating css.
document.body.style.cursor = *cursor-url*;
//OR
var elementToChange = document.getElementsByTagName("body")[0];
elementToChange.style.cursor = "url('cursor url with protocol'), auto";
or with jquery:
$("html").css("cursor: url('cursor url with protocol'), auto");
Firefox will not work unless you specify a default cursor after the imaged one!
other cursor keywords
Also remember that IE6 only supports .cur and .ani cursors.
If cursor doesn't change: In case you are moving the element under the cursor relative to the cursor position (e.g. element dragging) you have to force a redraw on the element:
// in plain js
document.getElementById('parentOfElementToBeRedrawn').style.display = 'none';
document.getElementById('parentOfElementToBeRedrawn').style.display = 'block';
// in jquery
$('#parentOfElementToBeRedrawn').hide().show(0);

hello with a fancy cursor!
</div>
</body>
<script type="text/javascript">
document.getElementsByTagName("body")[0].style.cursor = "url('http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur'), auto";

</html>
document.body.style.cursor = 'cursorurl';
Look at this page: http://www.webcodingtech.com/javascript/change-cursor.php. Looks like you can access cursor off of style. This page shows it being done with the entire page, but I'm sure a child element would work just as well.
document.body.style.cursor = 'wait';
