Image Spotlight effect

Note: Modifications to script by DD for code enhancements and bug fixes
Description: Cast an interactive "spotlight" on the image of your choice using this DHTML script. Move the light about using your mouse. This cool effect works in IE4+, degrading well with the rest.
Demo: Move your mouse over the following image if you're using IE4+
Step 1: Insert the following stylesheet into the <head> section of your page:
Step 2: Then, add the below code to the <BODY> section of your page:
Configure the image to be shown, and you're done!
Testing using two computers of varying speeds reveals that this effect requires a rather decent computer to render smoothly (ie: on a Celeron 400, the spotlight moves ratherly choppily). Also, the larger the image size (dimensions wise), the more resource-intensive the script becomes. Keep these two points in mind as you spotlight that huge photograph you took using your digital camera!
