DHTML countdown script

I'm developing a quiz program which creates HTML quizzes. I need a DHTML script which shows the time remaining (for example, 2 minutes). This DHTML should show the remaining time using a graphical appearance: for example, take a look at [login to view URL]~[login to view URL] and see the "Standard Clock" example. I need my script to be ***EXACTLY*** like the "Standard Clock" script but, instead of showing the clock, it should show the remaining time. As time passes, the circle should fill itself with a color: when the circle is 100% filled, time is elapsed. When I start the quiz, the circle is empty, then it fills itself clockwise. The max time should be a variable so that I can change it. The color used to fill the circle should be a variable so that I can change it. The script SHOULD BE CROSS-BROWSER (both PC and Mac): - IE >= 4: fully supported - Netscape >= 6: fully supported - Opera >= 6: fully supported - Mozilla >= 1: fully supported - Opera >= 5: appreciated - Netscape >= 4.5: appreciated If you want, you can add graphics to make it nicer, but it should be in XP style. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Cross-Platform
