when we move items with differ angles on screen 30 degrees after 90 after 245 degrees and we need to change images how we achieve this change ? eg a rocket moves and go around screen in random direction ?
using DHTML ,<div> ,...

use dhtml and <div>s...your icon can be in the div on a transparent background and you can use dhtml (js) to move the object around
