That sounds like a challenge!  :-)  (You said "virtually".

Here's a good reference for MacOSX ScreenSavers:
http://www.cocoadev.com/index.pl?ScreenSaver
As it indicates on this website:
ScreenSaver documentation is included in Mac OS X's Developer CD. Once the Developer packages are installed, the documentation can be found here:
	[Mac OS X 10.0] /Developer/Documentation/ReleaseNotes/ScreenSaver
	[Mac OS X 10.1] /Developer/Documentation/AdditionalTechnologies/ScreenSaver
	[Mac OS X 10.3] /Developer/Documentation/UserExperience?/Reference/ScreenSaver

   Off the wall idea: could a shell screen saver be made, which would then 
call off to the MetaCard engine itself with a *very* stripped down stack? 
True, I think would be really slow (maybe, depending on how exactly 
MetaCard draws in MacOSX, and whether that can be pushed directly into the 
NSView that the screensaver is given, and depending on whether the 
MetaCard system could be made a 'delegate' (Obj-C terminology - basically 
something inserted into a message-passing chain like by afterScript).

   Can the MetaCard engine by accessed like this (without having to pay a 
$1500 license for the embedded version..)
