[Macpartners] utility for HIDING cursor after period of inactivity?

[Duncan Kincaid]

does anyone know of a utility which will HIDE the cursor after a  
period of inactivity?
we have a mac mini running wKiosk which displays a flash movie on  
plasma displays. (we control the mac using Apple Remote Desktop).
the cursor is unsightly and 'burns' into the displays.
wKiosk does not offer such hide-cursor functionality (i have  
suggested they do).

thanks for any ideas!
