When using DHTML to do psychological experiments, you're likely to want to get rid of the mouse pointer as stimuli are presented. This is very easy fortunately. In principle you can have your mouse pointer look like anything that you can make a picture look like: First you create a bitmap (e.g., a blank one), and then you turn it into a .ico file. Then, on the body element (or any other element) of the HTML page you specify a cascading style sheet that includes the specification "cursor: url('mymouse.ico');" (of course 'mymouse' may be anything you like).
example: the George W. Bush fan DIV
Move your mouse over this text, you Georgey fan!
</div>
Here's the ico image that is used. You can make any bitmap in paint, for example, but that program won't save it as an .ico file. You can however copy and paste your design to IrfanView, from which you can save it as an .ico file.
