Functions (JavaScript) IE only
Try Me! Why Me?

	  
function moveIt() {
    if (document.all) {
	  sphere.style.top = parseInt(sphere.style.top) + 10;
      sphere.style.left = parseInt(sphere.style.left) - 25;
       if (parseInt(sphere.style.left) < 0) {
	   sphere.style.left = 900;
      }
	  if (parseInt(sphere.style.top) >600) {
	  sphere.style.top = 10;
      }
	}
	setTimeout('moveIt()', 100);
}

//function number two

function moveItwo() {
    if (document.all) {
	  sphere1.style.top = parseInt(sphere1.style.top) + 110;
      sphere1.style.left = parseInt(sphere.style.left) - 225;
       if (parseInt(sphere.style.left) < 0) {
	   sphere.style.left = 900;
      }
	  if (parseInt(sphere.style.top) >600) {
	  sphere.style.top = 10;
      }
	}
   }
   
}

My buttons to invoke my function

<input type="button" value="do it" onclick="" onMouseOver="moveIt()">
<input type="button" value="do in" onclick="" onMouseOver="moveItwo()">

    NOTES:

    I wrote this a few years back with the idea of just one broswer IE for the sake of understanding JavaScript in it's simples form.

    I'll write a cross browser version of this soon.
