Any module that has a "move" bang, such as !SystrayMove can produce "movement" if you use it with what's commonly called scripting. mzscript is probably the best way to do that as you can pause between "frames" much more easily, although you can certainly just use pause.dll with the !Execute bang. mzscript, however, allows for dynamic coordinates and adding / subtracting to them, so it would be easier to keep track of positions.
