Need to test a monitor attached to a running server, so I'm looking for 
an application/utility to display a large color graphic.  This must be 
possible to do without X because a splash screen comes up when this 
system boots.  The best graphic to display obviously would be some kind 
of fullscreen test pattern.  Anyone know where to get that?
