Hi Ted,

I think you can do this pretty easy in Object Graphics. You would draw the
box with an IDLgrPolyline object and then just change the stippling pattern
to mimic motion at each event (cursor motion or timing). The stippling
pattern is a bitmask that you pass with the linestyle keyword. Look at the
init method of IDLgrPolyline and the linestyle keyword.

In Direct Graphics it would be possible but not very pretty and lots of
code.
