Bring up the "world's" halo, by alt-clicking on the squeak desktop,  
and then click on its turquoise handle to bring up the world's Viewer.

If you type "mouse" into the search pane of that Viewer, you'll find  
that there are tiles available for mouseX and mouseY.  These are  
numeric-valued tiles that always report the current x and y  
coordinates of the mouse, in the World's own cartesian coordinate  
system.

Using these, the following script will make an object always follow  
the mouse:
