How is it possible to move more then one object at the same time, like this: http://www.ozones.com/crystal/

function run() {
count++;
for ( j = 0 ; j <= 9 ; j++ ) {
difftop[j] = Ypoint[j] - temptoplocation[j];
diffleft[j] = Xpoint[j] - templeftlocation[j];
temptoplocation[j] = temptoplocation[j] + difftop[j]/30;
templeftlocation[j] = templeftlocation[j] + diffleft[j]/30;
eval(layerstart+"a"+j+layerstyle+layerleft+" = templeftlocation["+j+"]");
eval(layerstart+"a"+j+layerstyle+layertop+" = temptoplocation["+j+"]"); }
setTimeout('run()', 10) }

This is part of Doc's code...this is what makes the balls orbit.
You can't make them move at 'exactly' the same time, but if within 1/1000 of a sec is good enough for you this will work.
Anyway, each ball is numbered, 0-9. In fact, without looking at any other parts of the code, we can see that the balls are named "a0,a1,a2,a3.....a9"
This script moves a'j', where 'j' is a number between, and inclusive of, 0 and 9.
Now, there are other parts of the code that control the movement, but this part is what controls moving all of the balls 'at the same time'.
It is the
for(j=0; j<=9; j++)
part that is important.
Get it??

I wrote a demonstration page that has multiple copies or instances of the same object moving on the same page. Take a look at the source for some ideas. It works for NN4 and IE5.

Very nice bug! I've been trying to do somthing similar on my page, thanks!
